Detailed Description

Wrappers for accessing functions by advanced users.

Note

This file contains Level-5 (Sol) functions. It requires: AuxParam.c, BlaFormat.c, BlaSparseBSR.c, BlaSparseCSR.c, SolAMG.c, SolBSR.c, and SolCSR.c

IMPORTANT: The wrappers DO NOT change the original matrix data. Users should shift the matrix indices in order to make the IA and JA to start from 0 instead of 1.
