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

flg - the result

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.
