Yule-Walker method for IIR filter design given an arbitrary magnitude response

Description

This implements a modified yule-walker method for estimating the coefficients of an IIR filter that best matches an arbitrary frequency response. This is a port from sci-lab's version here: yulewalk.sci and is distributed by the same license (CeCILLv2.0).
