#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.
|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.
