MatMatSolveTranspose
Solves A^T X = B, given a factored matrix.
Synopsis
#include "petscmat.h"
PetscErrorCode MatMatSolveTranspose(Mat A,Mat B,Mat X)
Neighborwise Collective on Mat
Input Parameters
 A   the factored matrix

 B   the righthandside matrix (dense matrix)

Output Parameter
 X   the result matrix (dense matrix)

Notes
The matrices B and X cannot be the same. I.e., one cannot
call MatMatSolveTranspose(A,X,X).
Notes
Most users should usually employ the simplified KSP interface for linear solvers
instead of working directly with matrix algebra routines such as this.
See, e.g., KSPCreate(). However KSP can only solve for one vector (column of X)
at a time.
When using SuperLU_Dist or MUMPS as a parallel solver, PETSc will use their functionality to solve multiple right hand sides simultaneously.
