+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:

+   <para>
+This is an Octave function.
+This version utilizes a Kaiser window to shape the frequency response of the designed filter. Tha number nb of bands and the desired attenuation at in the stop-band are given as parameters.
+   </para>
+   <para>
+The Kaiser window is multiplied by the ideal impulse response h(n)=a.sinc(a.n) and converted to its minimum-phase version by means of a Hilbert transform.

+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:

+//Parameters
+//Description
+//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,
+//
+//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
+//
+//fftw ("dwisdom", wisdom)
+//If wisdom is an empty string, then the wisdom used is cleared.
+//
+//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:
+//
+//"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.
+//
+//"measure"
+//In this case a range of algorithms to perform the transform is considered and the best is selected based on their execution time.
+//
+//"patient"
+//Similar to "measure", but a wider range of algorithms is considered.
+//
+//"exhaustive"
+//Like "measure", but all possible algorithms that may be used to treat the transform are considered.
+//
+//"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.

+//Description
+//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:
+//
+// Transform         Zero at x                  Pole at x
+// ----------------  -------------------------  ------------------------

+// S -> C S/Fc       gain: C/Fc                 gain: Fc/C

+//                   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 -> 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 -> C --------   gain: -x                   gain: -1/x
+//        S^2+FhFl   b=C/x (Fh-Fl)/2            b=C/x (Fh-Fl)/2
+// ----------------  -------------------------  ------------------------

+// ----------------  -------------------------  ------------------------
+// 
+//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:

+//Parameters 
+//x: Input.
+//y: Output.
+//window:        [real vector] of window-function values between 0 and 1; the data segment has the same length as the window. Default window shape is Hamming. [integer scalar] length of each data segment.  The default value is window=sqrt(length(x)) rounded up to the nearest integer power of 2; see 'sloppy' argument. 
+// overlap:      [real scalar] segment overlap expressed as a multiple of window or segment length.   0 <= overlap < 1, The default is overlap=0.5 .
+// Nfft:         [integer scalar] Length of FFT.  The default is the length of the "window" vector or has the same value as the scalar "window" argument.  If Nfft is larger than the segment length, "seg_len", the data segment is padded with "Nfft-seg_len" zeros.  The default is no padding. Nfft values smaller than the length of the data segment (or window) are ignored silently. 
+// Fs:           [real scalar] sampling frequency (Hertz); default=1.0
+// range:      'half',  'onesided' : frequency range of the spectrum is zero up to but not including Fs/2.  Power from negative frequencies is added to the positive side of the spectrum, but not at zero or Nyquist (Fs/2) frequencies.  This keeps power equal in time and spectral domains.  See reference [2]. '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'.
