# 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().
