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

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

Output Parameters

B -the transpose

Notes

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.
