MatMatSolveTranspose#

Solves A^T X = B, given a factored matrix.

Synopsis#

#include "petscmat.h" 
PetscErrorCode MatMatSolveTranspose(Mat A, Mat B, Mat X)

Neighbor-wise Collective

Input Parameters#

A - the factored matrix
B - the right-hand-side matrix (MATDENSE matrix)

Output Parameter#

X - the result matrix (dense matrix)

Note#

The matrices B and X cannot be the same. I.e., one cannot call MatMatSolveTranspose(A,X,X).
