-   <para>
-This function generates a Chebyshev type II filter with rs dB of stopband attenuation.</para>
-<para>If third parameter is scalar then,the fourth parameter takes in high or low, default value is low. The cutoff is pi*Wc radians.</para>
-<para>[b, a] = cheby2(n, Rp, [Wl, Wh]) indicates a band pass filter with edges pi*Wl and pi*Wh radians.</para>
-<para>[b, a] = cheby2(n, Rp, [Wl, Wh], ’stop’) indicates a band reject filter with edges pi*Wl and pi*Wh radians.</para>
-<para>[z, p, g] = cheby2(...) returns filter as zero-pole-gain rather than coefficients of the numerator and denominator polynomials.</para>
-<para>[...] = cheby2(...,’s’) returns a Laplace space filter, wp can be larger than 1 rad/sec.
