PETSc version 3.16.6
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,PetscReal,Vec,Vec,PetscReal,Mat,void*),void *ctx)
Logically Collective on TS
Input Parameters
| ts | - TS context obtained from TSCreate()
|
| 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)
|
| Udot | - time derivative of state vector
|
| shift | - shift to apply, see note below
|
| 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
