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 (
MATDENSEmatrix)
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).
