# MatSolveTranspose

Solves A' x = b, given a factored matrix.

### Synopsis

    #include "petscmat.h"
    PetscErrorCode  MatSolveTranspose(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 MatSolveTranspose(A,x,x).

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().
