Computes the symbolic part of the transpose of a matrix.

## Synopsis

    #include "petscmat.h"
    PetscErrorCode MatTransposeSymbolic(Mat A, Mat *B)

Collective

## Input Parameter

- A - the matrix to transpose

## Output Parameter

- B - the transpose. This is a complete matrix but the numerical portion is invalid. One can call `MatTranspose`(A,`MAT_REUSE_MATRIX`,&B) to compute the numerical portion.

## Note

This is not supported for many matrix types, use `MatTranspose()` in those cases
