LUSOL for Sparse Matrices using Sprsin? [message #78825] Thu, 22 December 2011 19:25

Hey guys,
I have a handy dandy sparse matrix that I made using SPRSIN (I tried
using coordinate storage and band storage formats but I don't have the
IDL analyst license so they would not work), and want to solve a
system of equations for this matrix using something similar to LUSOL
(or the backslash operator in matlab).
I know I can solve the system using LINBCG, but the whole point of
this is to compare the use of LINBCG to something similar to LUSOL
Is anyone familiar with a function that can do that using row-indexed
sparse matrices?
Thanks!
