KSPMatSolve
Solves a linear system with multiple right-hand sides stored as a MATDENSE. Unlike KSPSolve(), B and X must be different matrices.
Synopsis
#include "petscksp.h"
#include "petscmat.h"
PetscErrorCode KSPMatSolve(KSP ksp, Mat B, Mat X)
Input Parameters
| ksp | - iterative context
|
| B | - block of right-hand sides
|
Output Parameter
Notes
This is a stripped-down version of KSPSolve(), which only handles -ksp_view, -ksp_converged_reason, and -ksp_view_final_residual.
