<div class="refsection"><h3 class="title">Description</h3>
<p class="para">This is an Octave function.
This function returns the filter coefficients of a Dolph-Chebyshev window of length m supplied as input, to the output vector w.
The second parameter is the stop band attenuation of the Fourier transform in dB. The default value is 100 dB.</p></div>
