MatTransposeSetPrecursor#
Set the matrix from which the second matrix will receive numerical transpose data with a call to MatTranspose(A,MAT_REUSE_MATRIX,&B) when B was not obtained with MatTranspose(A,MAT_INITIAL_MATRIX,&B)
Synopsis#
#include "petscmat.h"
PetscErrorCode MatTransposeSetPrecursor(Mat mat, Mat B)
Collective
Input Parameter#
mat - the matrix to provide the transpose
Output Parameter#
B - the matrix to contain the transpose; it MUST have the nonzero structure of the transpose of A or the code will crash or generate incorrect results
Note#
Normally the use of MatTranspose(A, MAT_REUSE_MATRIX, &B) requires that B was obtained with a call to MatTranspose(A, MAT_INITIAL_MATRIX, &B). This
routine allows bypassing that call.
