PETSc version 3.17.5
MatMultAdd
Computes v3 = v2 + A * v1.
Synopsis
#include "petscmat.h"
PetscErrorCode MatMultAdd(Mat mat,Vec v1,Vec v2,Vec v3)
Neighbor-wise Collective on Mat
Input Parameters
| mat | - the matrix
|
| v1, v2 | - the vectors
|
Output Parameters
Notes
The vectors v1 and v3 cannot be the same. I.e., one cannot
call MatMultAdd(A,v1,v2,v1).
