TSSetMatStructure#

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
