MatMatSolve
Solves A X = B, given a factored matrix.
Synopsis
#include "petscmat.h"
PetscErrorCode MatMatSolve(Mat A,Mat B,Mat X)
Collective on Mat
Input Parameters
| mat | - the factored matrix
|
| b | - the right-hand-side vector
|
Output Parameter
x -the result vector
Notes
The vectors b and x cannot be the same. I.e., one cannot
call MatMatSolve(A,x,x).
Notes
Most users should employ the simplified KSP interface for linear solvers
instead of working directly with matrix algebra routines such as this.
See, e.g., KSPCreate().
