DMDATSIJacobianLocalFn#
A prototype of a local residual evaluation function for use with DMDA that would be passed to DMDATSSetIJacobianLocal()
Synopsis#
#include <petscts.h> 
PETSC_EXTERN_TYPEDEF typedef PetscErrorCode(DMDATSIJacobianLocalFn)(DMDALocalInfo *info, PetscReal t, void *x, void *xdot, PetscReal shift, Mat J, Mat B, void *ctx);
Calling Sequence#
- info - defines the subdomain to evaluate the residual on 
- t - time at which to evaluate the jacobian 
- x - array of local state information 
- xdot - time derivative at this state 
- shift - see - TSSetIJacobian()for the meaning of this parameter
- J - Jacobian matrix 
- B - matrix from which to construct the preconditioner; often same as - J
- ctx - optional context 
Note#
The deprecated DMDATSIJacobianLocal still works as a replacement for DMDATSIJacobianLocalFn *.
