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.
