MatMatTransposeSolve#

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

Synopsis#

#include "petscmat.h" 
PetscErrorCode MatMatTransposeSolve(Mat A, Mat Bt, Mat X)

Neighbor-wise Collective

Input Parameters#

A - the factored matrix
Bt - the transpose of right-hand-side matrix as a MATDENSE

Output Parameter#

X - the result matrix (dense matrix)

Note#

For MUMPS, it only supports centralized sparse compressed column format on the host processor for right hand side matrix. User must create B^T in sparse compressed row format on the host processor and call MatMatTransposeSolve() to implement MUMPS’ MatMatSolve().
