Sparse linear system solver

Hello,

I'm trying to solve a rather large coupled system with a 192000 by 192000 matrix, based on the cg_no_precon example. The problem seems to be that dcg_init doesn't take arrays, which have been allocated in the heap as an input. Does anyone know how I could circumvent that problem?

 

Kind regards,

 

Ben
