Hello,
I am trying to solve Ax=b problem, where A is a sparse matrix. The
matrix A is saved in compressed column format.
Currently I am looking at Sparse Blas
(http://math.nist.gov/spblas/original.html). It has a routine which
provides a functionality of compressed sparse column format triangular
solve. So, I need to convert A to a traingular matrix first?
Any other suggestions? I am doing this in C++.
