MatConvert

Converts a matrix to another matrix, either of the same or different type.

Synopsis

#include "petscmat.h" 
PetscErrorCode  MatConvert(Mat mat, MatType newtype,MatReuse reuse,Mat *M)

Collective on Mat

Input Parameters

	mat	- the matrix
	newtype	- new matrix type. Use MATSAME to create a new matrix of the same type as the original matrix.
	reuse	- denotes if the destination matrix is to be created or reused. Currently MAT_REUSE_MATRIX is only supported for inplace conversion, otherwise use MAT_INITIAL_MATRIX. Output Parameter:

M -pointer to place new matrix

C++ variants

Mat MatConvert(Mat A,MatType t)

MatConvert(A,t,MAT_INITIAL_MATRIX,&a); return a;

Notes

MatConvert() first creates a new matrix and then copies the data from the first matrix. A related routine is MatCopy(), which copies the matrix entries of one matrix to another already existing matrix context.
