-   <para>
-This function generates an elliptic or Cauer filter with rp dB of passband ripple and rs dB of stopband attenuation.</para>
-<para>[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.</para>
-<para>[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.</para>
-<para>[b,a] = ellip(n, Rp, Rs, [Wl, Wh], 'stop') band reject filter with edges pi*Wl and pi*Wh</para>
-<para>[z, p, g] = ellip(...) returns filter as zero-pole-gain.</para>
-<para>[...] = ellip(...,’s’) returns a Laplace space filter, wp can be larger than 1 rad/sec.
