EDIT: Use scipy.linalg over numpy.linalg.

Per my previous post, I mistakenly referenced numpy.linalg and scipy.linalg as if they were the same.  Upon looking deeper at the documentation for scipy.linalg it clearly states the following:

scipy.linalg contains all the functions in numpy.linalg. plus some other more advanced ones not contained in numpy.linalg
Another advantage of using scipy.linalg over numpy.linalg is that it is always compiled with BLAS/LAPACK support, while for numpy this is optional. Therefore, the scipy version might be faster depending on how numpy was installed.
Therefore, unless you don’t want to add scipy as a dependency to your numpy program, use scipy.linalg instead of numpy.linalg

So for all my purposes, I will only use scipy.linalg.
