PetscErrorCode DMDATSSetRHSJacobianLocal(DM dm,DMDATSRHSJacobianLocal func,void *ctx)
Logically Collective

Input Arguments

dm - DM to associate callback with
func - local RHS Jacobian evaluation routine
ctx - optional context for local jacobian evaluation

Calling sequence for func

func(DMDALocalInfo* info,PetscReal t,void* x,Mat J,Mat B,void *ctx);

info - DMDALocalInfo defining the subdomain to evaluate the residual on
t - time at which to evaluate residual
x - array of local state information
J - Jacobian matrix
B - preconditioner matrix; often same as J
ctx - optional context passed above
