#393: invfreq function missing

 Priority:  normal        |   Milestone:          
Component:  scipy.signal  |     Version:          
 Severity:  normal        |    Keywords:

 Coming from octave, I used to use invfreq* function to fit a filter to
 frequency response data. I have not seen an equivalent function in
 scipy.signal

 Here the URI of the octave function :
 http://octave.cvs.sourceforge.net/octave/octave-
 forge/main/signal/inst/invfreqs.m?rev=HEAD&content-type=text/plain

 I've began to write this function in python (see attached file) but I'll
 follow adding matlab algorithm.
