MatTranspose
Computes an in-place or out-of-place transpose of a matrix.
Synopsis
#include "petscmat.h"
PetscErrorCode MatTranspose(Mat mat,MatReuse reuse,Mat *B)
Collective on Mat
Input Parameter
Output Parameters
B -the transpose
Notes
If you use MAT_INPLACE_MATRIX then you must pass in &mat for B
MAT_REUSE_MATRIX causes the B matrix from a previous call to this function with MAT_INITIAL_MATRIX to be used
Consider using MatCreateTranspose() instead if you only need a matrix that behaves like the transpose, but don't need the storage to be changed.
