Hi,
I am having the same problem as mentioned here:
http://www.scipy.net/pipermail/scipy-user/2004-December/003910.html
Attached is a small example V6 .mat file that demonstrates the problem (scipy 0.3.2).
A collegue says it works on his (older) scipy. I couldn't find where
to download the old versions of scipy.
thanks,
Simon.
