[SciPy-dev] scipy.signal.signaltools: filtfilt calls missing function

The filtfilt() function calls lfilter_zi, which is absent from scipy.  A 
version of it is in the Cookbook: 
http://www.scipy.org/Cookbook/FiltFilt.  It looks to me like a bit of 
reworking would be in order before adding it to scipy; it is using matrices.

I hope this can be fixed before the 0.7 release.

Is it essential that I create a ticket, or is this email sufficient?
