Hi,
Along the lines of python's numarray [1], we need some way of
operating pointwise (and inner/outer operations) on Mat/Vec objects.
In particular, we need things like the following:

Simon,
There is not because what does MatSet() mean for a sparse matrix?
Make it dense, just set all the current nonzeros, error? You tell us,
I could live with either of the later two but don't really like the

BTW: possibly related note, are you using dense matrices

to represent just 2-arrays; that is, not as representations of linear
operators. If so, I do not think this is the correct approach! Conceptually

I am not sure I understand the fine difference. As far as we are
concerned, all the operations which we are doing (point wise addition,
