TSAdjointSetRHSJacobian

Sets the function that computes the Jacobian of G w.r.t. the parameters p where y_t = G(y,p,t), as well as the location to store the matrix.

Synopsis

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

Input Parameters

ts - The TS context obtained from TSCreate()
func - The function

Calling sequence of func

func (TS ts,PetscReal t,Vec y,Mat A,void *ctx);
t - current timestep
y - 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

Keywords
