Hello,
I may be missing it somewhere, but I am surprised there is no function for
scaling arrays in MathArrays.java or somewhere else.

I have wondered about the public scoping of arrays myself for that same reason.
I also write image processing code, and the arrays can be quite large,

Gilles,
I think it will be difficult (for me, at least) to provide a general method for
testing sampling across all multivariate distributions. I imagine it can be
done, but I would prefer for now just to make it an abstract method and expect

That may have been a dumb question. I was thinking there were multiple NOTICE
