MatKAIJSetS#

Set the S matrix describing the shift action of the MATKAIJ 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 MATKAIJ 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 MATKAIJ matrix.

The S matrix is copied, so the user can destroy this array.
