Hi All,

There is a small bug in the initial conditions parameter in ellipap() in the filter_design.py module:

File "/users/sransom/lib/python2.3/site-packages/scipy/signal/filter_design.py", line 1049, in ellipap disp=0) File "/users/sransom/lib/python2.3/site-packages/scipy/optimize/optimize.py", line 140, in fmin N = len(x0) TypeError: len() of unsized object

Fixed in SVN. Would you mind writing a test to see whether ellipap gives the correct answer? Thanks Stéfan
