<title>Description</title>
<para>
This is an Octave function.
This function resamples in the input sequence x supplied by a factor of p/q. If x is a matrix, then every column is resampled changing the sample rate of x by a factor of p/q.
This is performed using a polyphase algorithm. The impulse response h, given as parameter 4, of the antialiasing filter is either specified or designed with a Kaiser-windowed sinecard.
