TSSetIJacobianP#
Sets the function that computes the Jacobian of F w.r.t. the parameters P where F(Udot,U,t) = G(U,P,t), as well as the location to store the matrix.
Synopsis#
#include <petscts.h>  
PetscErrorCode TSSetIJacobianP(TS ts, Mat Amat, PetscErrorCode (*func)(TS ts, PetscReal t, Vec U, Vec Udot, PetscReal shift, Mat A, void *ctx), void *ctx)
Logically Collective
Input Parameters#
Calling sequence of func#
- ts - the - TScontext
- t - current timestep 
- U - input vector (current ODE solution) 
- Udot - time derivative of state vector 
- shift - shift to apply, see note below 
- A - output matrix 
- ctx - [optional] user-defined function context 
Note#
Amat has the same number of rows and the same row parallel layout as u, Amat has the same number of columns and parallel layout as p
