PetscErrorCode MatMatInterpolate(Mat A, Mat x, Mat *y)
Neighbor-wise Collective
Input Parameters#
A - the matrix
x - the input dense matrix
Output Parameter#
y - the output dense matrix

This allows one to use either the restriction or interpolation (its transpose)
matrix to do the interpolation. y matrix can be reused if already created with the proper sizes,
otherwise it will be recreated. y must be initialized to NULL if not supplied.
