Subject: [ublas] Inversion of a sparse matrix
From: Moritz Lenz (mlenz_at_[hidden])

I'm looking for an implementation that inverts a sparse matrix, and
returns a "full" (or dense, or whatever it's called...) matrix.

I currently assign it to a dense matrix and use the LU-decomposition
which I found here:
but it's rather slow, and currently the bottleneck of my program - any
thoughts on how to improve it are very welcome.
