TSRHSJacobianPFn#

A prototype of a 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 that would be passed to TSSetRHSJacobianP()

Synopsis#

#include <petscts.h> 
PETSC_EXTERN_TYPEDEF typedef PetscErrorCode(TSRHSJacobianPFn)(TS ts, PetscReal t, Vec U, Mat A, void *ctx);

Calling Sequence#

ts - the TS context
t - current timestep
U - input vector (current ODE solution)
A - output matrix
ctx - [optional] user-defined function context

Note#

The deprecated TSRHSJacobianP still works as a replacement for TSRHSJacobianPFn *.

Level#

beginner
