+   <para>
+If the FREQ argument is a vector (of frequencies) the spectrum is calculated using the polynomial method and the METHOD argument is ignored.  For scalar FREQ, an integer power of 2, or METHOD = "FFT", causes the spectrum to be calculated by FFT. Otherwise, the spectrum is calculated as a polynomial.  It may be computationally more efficient to use the FFT method if length of the model is not much smaller than the number of frequency values.  The spectrum is scaled so that spectral energy (area under spectrum) is the same as the time-domain energy (mean square of the signal).

+Transform a s-plane filter specification into a z-plane specification.  Filters can be specified in either zero-pole-gain or transfer function form.  The input form does not have to match the output form.  1/T is the sampling frequency represented in the z plane.
+   </para>
+   <para>
+Note: this differs from the bilinear function in the signal processing toolbox, which uses 1/T rather than T.
+   </para>
+   <para>
+Theory: Given a piecewise flat filter design, you can transform it from the s-plane to the z-plane while maintaining the band edges by means of the bilinear transform. This maps the left hand side of the s-plane into the interior of the unit circle. The mapping is highly non-linear, so you must design your filter with band edges in the s-plane positioned at 2/T tan(w*T/2) so that they will be positioned at w after the bilinear transform is complete.

+   <para>
+This is an Octave function.
+Wisdom data can be used to significantly accelerate the calculation of the FFTs, but implies an initial cost in its calculation. When the FFTW libraries are initialized, they read a system wide wisdom
+file (typically in /etc/fftw/wisdom), allowing wisdom to be shared between applications other than Octave. Alternatively, the fftw function can be used to import wisdom. For example,
+   </para>
+   <para>
+wisdom = fftw ("dwisdom")
+will save the existing wisdom used by Octave to the string wisdom. This string can then be saved to a file and restored using the save and load commands respectively. This existing wisdom can be re
+imported as follows
+   </para>
+   <para>
+fftw ("dwisdom", wisdom)
+If wisdom is an empty string, then the wisdom used is cleared.
+   </para>
+   <para>
+During the calculation of Fourier transforms further wisdom is generated. The fashion in which this wisdom is generated is also controlled by the fftw function. There are five different manners in which
+the wisdom can be treated:
+   </para>
+   <para>
+"estimate"
+Specifies that no run-time measurement of the optimal means of calculating a particular is performed, and a simple heuristic is used to pick a (probably sub-optimal) plan. The advantage of this method
+is that there is little or no overhead in the generation of the plan, which is appropriate for a Fourier transform that will be calculated once.
+   </para>
+   <para>
+"measure"
+In this case a range of algorithms to perform the transform is considered and the best is selected based on their execution time.
+   </para>
+   <para>
+"patient"
+Similar to "measure", but a wider range of algorithms is considered.
+   </para>
+   <para>
+"exhaustive"
+Like "measure", but all possible algorithms that may be used to treat the transform are considered.
+   </para>
+   <para>
+"hybrid"
+As run-time measurement of the algorithm can be expensive, this is a compromise where "measure" is used for transforms up to the size of 8192 and beyond that the "estimate" method is used.
+   </para>
+   <para>
+The default method is "estimate". The current method can be queried with
+   </para>
+   <para>
+method = fftw ("planner")
+or set by using
+   </para>
+   <para>
+fftw ("planner", method)

+   <para>
+This is an Octave function.
+The vector f contains pairs of frequency band edges in the range [0,1]. The vector m specifies the magnitude response for each band. The values of m must be zero for all stop bands and must have the
+same magnitude for all pass bands. The deviation of the filter dev can be specified as a scalar or a vector of the same length as m. The optional sampling rate fs can be used to indicate that f is in
+Hz in the range [0,fs/2].
+   </para>
+   <para>
+The returned value n is the required order of the filter (the length of the filter minus 1). The vector Wn contains the band edges of the filter suitable for passing to fir1. The value beta is the
+parameter of the Kaiser window of length n+1 to shape the filter. The string ftype contains the type of filter to specify to fir1.
+   </para>
+   <para>
+The Kaiser window parameters n and beta are computed from the relation between ripple (A=-20*log10(dev)) and transition width (dw in radians) discovered empirically by Kaiser:

+   <p class="para">Transform a s-plane filter specification into a z-plane specification.  Filters can be specified in either zero-pole-gain or transfer function form.  The input form does not have to match the output form.  1/T is the sampling frequency represented in the z plane.</p>
+   <p class="para">Note: this differs from the bilinear function in the signal processing toolbox, which uses 1/T rather than T.</p>
+   <p class="para">Theory: Given a piecewise flat filter design, you can transform it from the s-plane to the z-plane while maintaining the band edges by means of the bilinear transform. This maps the left hand side of the s-plane into the interior of the unit circle. The mapping is highly non-linear, so you must design your filter with band edges in the s-plane positioned at 2/T tan(w*T/2) so that they will be positioned at w after the bilinear transform is complete.</p></div>

+Frequencies are normalized to the Nyquist frequency in the range [0,1].
+Rp is measured in decibels and is the allowable passband ripple, and Rs is also in decibels and is the minimum attenuation in the stop band.
+If ws&gt;wp, the filter is a low pass filter. If wp&gt;ws, the filter is a high pass filter.
+If wp and ws are vectors of length 2, then the passband interval is defined by wp the stopband interval is defined by ws.
+If wp is contained within the lower and upper limits of ws, the filter is a band-pass filter. If ws is contained within the lower and upper limits of wp the filter is a band-stop or band-reject filter.</p></div>

+[b, a] = ellip(n, Rp, Rs, Wp) indicates low pass filter with order n, Rp decibels of ripple in the passband and a stopband Rs decibels down and cutoff of pi*Wp radians. If the fifth argument is high, then the filter is a high pass filter.
+[b, a] = ellip(n, Rp, Rs, [Wl, Wh]) indictaes band pass filter with band pass edges pi*Wl and pi*Wh. If the fifth argument is stop, the filter is a band reject filter.
+[z, p, g] = ellip(...) returns filter as zero-pole-gain.
+[...] = ellip(...,’s’) returns a Laplace space filter, w can be larger than 1.

+   <p class="para">This is an Octave function.
+This function computes the minimum filter order of an elliptic filter with the desired response characteristics.
+Stopband frequency ws and passband frequency wp specify the the filter frequency band edges.
+Frequencies are normalized to the Nyquist frequency in the range [0,1].
+Rp is measured in decibels and is the allowable passband ripple and Rs is also measured in decibels and is the minimum attenuation in the stop band.
+If ws&gt;wp then the filter is a low pass filter. If wp&gt;ws, then the filter is a high pass filter.
+If wp and ws are vectors of length 2, then the passband interval is defined by wp and the stopband interval is defined by ws.
+If wp is contained within the lower and upper limits of ws, the filter is a band-pass filter. If ws is contained within the lower and upper limits of wp, the filter is a band-stop or band-reject filter.</p></div>

+   <p class="para">This is an Octave function.
+Wisdom data can be used to significantly accelerate the calculation of the FFTs, but implies an initial cost in its calculation. When the FFTW libraries are initialized, they read a system wide wisdom
+file (typically in /etc/fftw/wisdom), allowing wisdom to be shared between applications other than Octave. Alternatively, the fftw function can be used to import wisdom. For example,</p>
+   <p class="para">wisdom = fftw (&#0034;dwisdom&#0034;)
+will save the existing wisdom used by Octave to the string wisdom. This string can then be saved to a file and restored using the save and load commands respectively. This existing wisdom can be re
+imported as follows</p>
+   <p class="para">fftw (&#0034;dwisdom&#0034;, wisdom)
+If wisdom is an empty string, then the wisdom used is cleared.</p>
+   <p class="para">During the calculation of Fourier transforms further wisdom is generated. The fashion in which this wisdom is generated is also controlled by the fftw function. There are five different manners in which
+the wisdom can be treated:</p>
+   <p class="para">&#0034;estimate&#0034;
+Specifies that no run-time measurement of the optimal means of calculating a particular is performed, and a simple heuristic is used to pick a (probably sub-optimal) plan. The advantage of this method
+is that there is little or no overhead in the generation of the plan, which is appropriate for a Fourier transform that will be calculated once.</p>
+   <p class="para">&#0034;measure&#0034;
+In this case a range of algorithms to perform the transform is considered and the best is selected based on their execution time.</p>
+   <p class="para">&#0034;patient&#0034;
+Similar to &#0034;measure&#0034;, but a wider range of algorithms is considered.</p>
+   <p class="para">&#0034;exhaustive&#0034;
+Like &#0034;measure&#0034;, but all possible algorithms that may be used to treat the transform are considered.</p>
+   <p class="para">&#0034;hybrid&#0034;
+As run-time measurement of the algorithm can be expensive, this is a compromise where &#0034;measure&#0034; is used for transforms up to the size of 8192 and beyond that the &#0034;estimate&#0034; method is used.</p>
+   <p class="para">The default method is &#0034;estimate&#0034;. The current method can be queried with</p>
+   <p class="para">method = fftw (&#0034;planner&#0034;)
+or set by using</p>

+   <p class="para">&#0034;MinPeakDistance&#0034;:
+Minimum separation between (positive integer). Peaks separated by less than this distance are considered a single peak.  This distance is also used to fit a second order polynomial to the peaks to estimate their width, therefore it acts as a smoothing parameter.  Default value 4.</p>
+   <p class="para">&#0034;MinPeakWidth&#0034;:
+Minimum width of peaks (positive integer). The width of the peaks is estimated using a parabola fitted to the neighborhood of each peak.  The neighborhood size is equal to the value of &#0034;MinPeakDistance&#0034;. The width is evaluated at the half height of the peak with baseline at &#0034;MinPeakHeight&#0034;. Default value 2.</p>

+Tells the function that data takes positive and negative values. The base-line for the peaks is taken as the mean value of the function.  This is equivalent as passing the absolute value of the data after removing the mean.</p></div>

+   <p class="para">goertzel(X,INDVEC)
+Computes the DFT of X at indices INDVEC using the second order algorithm along
+the first non-singleton dimension. Elements of INDVEC must be positive integers
+less than the length of the first non-singleton dimension. If INDVEC is empty
+the DFT is computed at all indices along the first non-singleton dimension
+goertzel(X,INDVEC,DIM)
+Implements the algorithm along dimension DIM
+In general goertzel is slower than fft when computing the DFT for all indices
+along a particular dimension. However it is computationally more efficient when
+the DFT at only a subset of indices is desired

+OPT is the constant of phase modulation.
+opt = pi/max(max(abs(x))) by default
+Phase lies between -pi and +pi
+&#0039;pwm&#0039;      Pulse width modulation
+opt=&#0039;left&#0039; corresponds to left justified pulses.
+opt=&#0039;centered&#0039; correspondes to centered pulses.
+The default value of opt is &#0039;left&#0039;.
+&#0039;ppm&#0039;      Pulse position modulation
+opt is a scalar between 0 and 1 which specifies the pulse
+width in fractions of the carrier period with default value 0.1.
+&#0039;qam&#0039;       Quadrature amplitude modulation
+opt is a matrix of the same size as X which is modulated in
+quadrature with x.</p>
+   <p class="para">If x is a matrix, its columns are modulated.
+Example
+y  =</p>
+   <p class="para">1.    1.    0.    0.

If &#0034;window&#0034; is a scalar, each segment has a length of &#0034;window&#0034; and a Hamming window is used. The spectral density is the mean of the periodograms, scaled so that area under the spectrum is the same as the mean square of the data.  This equivalence is supposed to be exact, but in practice there is a mismatch of up to 0.5% when comparing area under a periodogram with the mean square of the data.</p></div>

+   <p class="para">This is an Octave function.
+Theory: Given a low pass filter represented by poles and zeros in the splane, you can convert it to a low pass, high pass, band pass or band stop by transforming each of the poles and zeros
+individually. The following table summarizes the transformation:</p>
+   <p class="para">Transform         Zero at x                  Pole at x
+----------------  -------------------------  ------------------------
+Low Pass          zero: Fc x/C               pole: Fc x/C
+S -&gt; C S/Fc       gain: C/Fc                 gain: Fc/C
+----------------  -------------------------  ------------------------
+High Pass         zero: Fc C/x               pole: Fc C/x
+S -&gt; C Fc/S       pole: 0                    zero: 0
+gain: -x                   gain: -1/x
+----------------  -------------------------  ------------------------
+Band Pass         zero: b +- sqrt(b^2-FhFl)  pole: b +- sqrt(b^2-FhFl)
+S^2+FhFl   pole: 0                    zero: 0
+S -&gt; C --------   gain: C/(Fh-Fl)            gain: (Fh-Fl)/C
+S(Fh-Fl)   b=x/C (Fh-Fl)/2            b=x/C (Fh-Fl)/2
+----------------  -------------------------  ------------------------
+Band Stop         zero: b +- sqrt(b^2-FhFl)  pole: b +- sqrt(b^2-FhFl)
+S(Fh-Fl)   pole: +-sqrt(-FhFl)        zero: +-sqrt(-FhFl)
+S -&gt; C --------   gain: -x                   gain: -1/x
+S^2+FhFl   b=C/x (Fh-Fl)/2            b=C/x (Fh-Fl)/2
+----------------  -------------------------  ------------------------
+Bilinear          zero: (2+xT)/(2-xT)        pole: (2+xT)/(2-xT)
+2 z-1        pole: -1                   zero: -1
+S -&gt; - ---        gain: (2-xT)/T             gain: (2-xT)/T
+T z+1
+----------------  -------------------------  ------------------------</p>
+   <p class="para">where C is the cutoff frequency of the initial lowpass filter, Fc is the edge of the target low/high pass filter and [Fl,Fh] are the edges of the target band pass/stop filter. With abundant tedious
+algebra, you can derive the above formulae yourself by substituting the transform for S into H(S)=S-x for a zero at x or H(S)=1/(S-x) for a pole at x, and converting the result into the form:</p>
+   <p class="para">H(S)=g prod(S-Xi)/prod(S-Xj)</p></div>

+   <para>
+This is an Octave function.
+Theory: Given a low pass filter represented by poles and zeros in the splane, you can convert it to a low pass, high pass, band pass or band stop by transforming each of the poles and zeros
+individually. The following table summarizes the transformation:
+   </para>
+   <para>
+Transform         Zero at x                  Pole at x
+----------------  -------------------------  ------------------------
+Low Pass          zero: Fc x/C               pole: Fc x/C
+S -&gt; C S/Fc       gain: C/Fc                 gain: Fc/C
+----------------  -------------------------  ------------------------
+High Pass         zero: Fc C/x               pole: Fc C/x
+S -&gt; C Fc/S       pole: 0                    zero: 0
+gain: -x                   gain: -1/x
+----------------  -------------------------  ------------------------
+Band Pass         zero: b +- sqrt(b^2-FhFl)  pole: b +- sqrt(b^2-FhFl)
+S^2+FhFl   pole: 0                    zero: 0
+S -&gt; C --------   gain: C/(Fh-Fl)            gain: (Fh-Fl)/C
+S(Fh-Fl)   b=x/C (Fh-Fl)/2            b=x/C (Fh-Fl)/2
+----------------  -------------------------  ------------------------
+Band Stop         zero: b +- sqrt(b^2-FhFl)  pole: b +- sqrt(b^2-FhFl)
+S(Fh-Fl)   pole: +-sqrt(-FhFl)        zero: +-sqrt(-FhFl)
+S -&gt; C --------   gain: -x                   gain: -1/x
+S^2+FhFl   b=C/x (Fh-Fl)/2            b=C/x (Fh-Fl)/2
+----------------  -------------------------  ------------------------
+Bilinear          zero: (2+xT)/(2-xT)        pole: (2+xT)/(2-xT)
+2 z-1        pole: -1                   zero: -1
+S -&gt; - ---        gain: (2-xT)/T             gain: (2-xT)/T
+T z+1
+----------------  -------------------------  ------------------------
+   </para>
+   <para>
+where C is the cutoff frequency of the initial lowpass filter, Fc is the edge of the target low/high pass filter and [Fl,Fh] are the edges of the target band pass/stop filter. With abundant tedious
+algebra, you can derive the above formulae yourself by substituting the transform for S into H(S)=S-x for a zero at x or H(S)=1/(S-x) for a pole at x, and converting the result into the form:
+   </para>
+   <para>
+H(S)=g prod(S-Xi)/prod(S-Xj)

'whole', 'twosided' : frequency range of the spectrum is  -Fs/2 to Fs/2, with negative frequencies stored in "wrap around" order after the positive frequencies; e.g. frequencies for a 10-point 'twosided' spectrum are 0 0.1 0.2 0.3 0.4 0.5 -0.4 -0.3 -0.2 -0.1 'shift', 'centerdc' : same as 'whole' but with the first half of the spectrum swapped with second half to put the zero-frequency value in the middle. (See "help fftshift". If data (x and y) are real, the default range is 'half', otherwise default range is 'whole'.</para></listitem></varlistentry>
