<div class="refsection"><h3 class="title">Description</h3>
<p class="para">This is an Octave function.
This function computes the filter coefficients for all Savitzsky-Golay smoothing filters of order p for length n (odd).
m can be used in order to get directly the mth derivative; ts is a scaling factor.</p></div>
