[SciPy-Dev] sparse rmatvec and maxentropy

[josef.pktd at gmail.com]

I don't know much about these two parts of scipy.

Running an example for scipy.maxentropy raises an exception after
upgrading to scipy trunk

I didn't manage to find out with a  Trac search whether rmatvec still exists.

scipy.maxentropy maxentutils is still using it.
