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#
X - block of solutions
Notes#
This is a stripped-down version of KSPSolve()
, which only handles -ksp_view
, -ksp_converged_reason
, -ksp_converged_rate
, and -ksp_view_final_residual
.
