PETSc version 3.15.5
MatSolveTranspose
Solves A' x = b, given a factored matrix.
Synopsis
#include "petscmat.h"
PetscErrorCode MatSolveTranspose(Mat mat,Vec b,Vec x)
Neighbor-wise Collective on Mat
Input Parameters
| mat | - the factored matrix
|
| b | - the right-hand-side vector
|
Output Parameter
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().
