MatMatInterpolateAdd#
\(Y = W + A*X\) or \(W + A^T*X\) depending on the shape of A
Synopsis#
#include "petscmat.h"
PetscErrorCode MatMatInterpolateAdd(Mat A, Mat x, Mat w, Mat *y)
Neighbor-wise Collective
Input Parameters#
A - the matrix
x - the input dense matrix to be multiplied
w - the input dense matrix to be added to the result
Output Parameter#
y - the output dense matrix
Note#
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.
