Supporting scipy.linalg in nopython mode?

[Phyks]

Hi,

From my tests and while looking at the docs, it seems scipy.linalg module is not supported in nopython mode.

However, scipy.linalg.expm is the only implementation of matrix exponentiation in scipy and numpy, as far as I know, and having not supported can be blocking for some applications.

For now, I worked around it by isolating the part of my code that needed scipy.linalg.expm and wrapping the rest in a JIT with nopythonmode, but this may not be always possible.

Thanks!
