TSGetRHSJacobianP

Gets the function that computes the Jacobian of G w.r.t. the parameters P where U_t = G(U,P,t), as well as the location to store the matrix.

Synopsis

#include "petscts.h"  
PetscErrorCode TSGetRHSJacobianP(TS ts,Mat *Amat,PetscErrorCode (**func)(TS,PetscReal,Vec,Mat,void*),void **ctx)
Logically Collective on TS

Input Parameters

ts -TS context obtained from TSCreate()

Output Parameters

Amat - JacobianP matrix
func - function
ctx - [optional] user-defined function context

Calling sequence of func

func (TS ts,PetscReal t,Vec y,Mat A,void *ctx);
t - current timestep
U - input vector (current ODE solution)
A - output matrix
ctx - [optional] user-defined function context

Notes

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
