MatSolves
Solves A x = b, given a factored matrix, for a collection of vectors
Synopsis
#include "petscmat.h"
PetscErrorCode MatSolves(Mat mat,Vecs b,Vecs x)
Neighbor-wise Collective on Mat and Vecs
Input Parameters
| mat | - the factored matrix
|
| b | - the right-hand-side vectors
|
Output Parameter
x -the result vectors
Notes
The vectors b and x cannot be the same. I.e., one cannot
call MatSolves(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().
