# MatKAIJSetS

Set the S matrix describing the shift action of the KAIJ matrix

### Synopsis

    #include "petscmat.h"
    PetscErrorCode MatKAIJSetS(Mat A,PetscInt p,PetscInt q,const PetscScalar S[])

Logically Collective; the entire S is stored independently on all processes.

### Input Parameters

| A | - the KAIJ matrix
| p | - the number of rows in S
| q | - the number of columns in S
| S | - the S matrix, in form of a scalar array in column-major format

Notes: The dimensions p and q must match those of the transformation matrix T associated with the KAIJ matrix. The S matrix is copied, so the user can destroy this array.
