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 or MAT_REUSE_MATRIX

B -the transpose

If you pass in &mat for B the transpose will be done in place, for example MatTranspose(mat,MAT_REUSE_MATRIX,&mat);

Consider using MatCreateTranspose() instead if you only need a matrix that behaves like the transpose, but don't need the storage to be changed.
