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
Input Parameter#
Output Parameters#
Amat - JacobianP matrix
func - function
ctx - [optional] user-defined function context
Calling sequence of func#
PetscErrorCode 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
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
