What I see form a quick browse of the PR, is that we can get most of linalg to
work on many matrices (2d arrays) at the same time.
(It's the first time we get generalized u-functions that are targeted to users,
IISIC, if I see it correctly)

I would also like to see these added, and we will have many cases where this
will be very useful in statistics and statsmodels.

The code in the aforementioned PR would be very useful to me in performance 
critical areas of my code. So much so in fact that I've actually rolled my own 
functions in cython to do what I need. I'd be happy if the functionality was 
available by default in numpy though.

[Numpy-discussion] Moving linalg c code

2013-04-03 Thread Charles R Harris
Hi All,

There is a PR  that adds some
blas and lapack functions to numpy. I'm thinking that if that PR is merged
it would be good to move all of the blas and lapack functions, including
the current ones in numpy/linalg into a single directory somewhere in
numpy/core/src. So there are two questions here: should we be adding the
new functions, and if so, should we consolidate all the blas and lapack C
code into its own directory somewhere in numpy/core/src.

Thoughts?

Chuck
