[Pyublas] wrapping existing ublas matrices

[Ben]

hello --

is it possible for a numpy_* class to wrap the memory of an existing
ublas vector / matrix, without copying? i have existing ublas code
i'd like to expose to python, and the matrices are too huge to copy.

best, ben

This was the premise of "pylinear", a prior project of mine, which attempted
to reimplement a numpy-like array package on top of wrapped ublas types.

Code is here:
http://git.tiker.net/pylinear.git
git clone http://git.tiker.net/trees/pylinear.git

I personally have abandoned this approach in favor of writing my code as
templates that can deal with numpy_{matrix,vector} and ublas::{matrix,vector}.
