TSGetIJacobianP#

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

Synopsis#

#include <petscts.h>  
PetscErrorCode TSGetIJacobianP(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 Parameter#

ts - TS context obtained from TSCreate()

Output Parameters#

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

Calling sequence of `func`#

ts - the TS context
t - current timestep
U - input vector (current ODE solution)
Udot - time derivative of state vector
shift - shift to apply, see the note in TSSetIJacobian()
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
