MatTranspose

Computes an in-place or out-of-place transpose of a matrix.

#include "petscmat.h" 
PetscErrorCode MatTranspose(Mat mat,MatReuse reuse,Mat *B)

Collective on Mat

	mat	- the matrix to transpose
	reuse	- either MAT_INITIAL_MATRIX, MAT_REUSE_MATRIX, or MAT_INPLACE_MATRIX

B -the transpose

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.
