Manu,

I am using GSL as library for the vector storage module I am writing. It
has some support for LU decomposition but I do not know if it can handle
sparse the sparse matrix structure that SPICE builds. It seems that
matrices in GSL are handled as memory blocks. This is very bad if the 
matrix is sparse, there is a huge waste of memory and, I think, the code
is less performant. 

Paolo
