PETSc version 3.16.6
MatIsHermitianTranspose
Test whether a matrix is another one's Hermitian transpose,
Synopsis
#include "petscmat.h"
PetscErrorCode MatIsHermitianTranspose(Mat A,Mat B,PetscReal tol,PetscBool *flg)
Collective on Mat
Input Parameters
| A | - the matrix to test
|
| B | - the matrix to test against, this can equal the first parameter
|
Output Parameters
Notes
Only available for SeqAIJ/MPIAIJ matrices. The sequential algorithm
has a running time of the order of the number of nonzeros; the parallel
test involves parallel copies of the block-offdiagonal parts of the matrix.
