sets the relationship between the nonzero structure of the RHS Jacobian matrix to the IJacobian matrix.
Synopsis#
#include "petscts.h"
PetscErrorCode TSSetMatStructure(TS ts, MatStructure str)
Logically Collective
Input Parameters#
ts - the time-stepper
str - the structure (the default is
UNKNOWN_NONZERO_PATTERN)
Note#
When the relationship between the nonzero structures is known and supplied the solution process can be much faster
