MatSolve
Solves A x = b, given a factored matrix.
Synopsis
#include "petscmat.h"
int MatSolve(Mat mat,Vec b,Vec x)
Collective on Mat and Vec
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 MatSolve(A,x,x).
Notes
Most users should employ the simplified SLES interface for linear solvers
instead of working directly with matrix algebra routines such as this.
See, e.g., SLESCreate().
