The CVODEs Jacobian interface for a direct dense Jacobian.
- Parameters
-
N the problem size t The current time of the system y The current state vector (in CVODE format) ydot The RHS vector to be populated (in CVODE format) jac The Jacobian matrix (in CVODE format) to output to f User data set during CVODEs setup (e.g. the system pressure) tmp1 Temporary storage used by CVODEs tmp2 Temporary storage used by CVODEs tmp3 Temporary storage used by CVODEs
- Returns
- cvode_return_code The CVODE output constant returned (see sec B.2 of CVODE documentation), currently always returns CV_SUCCESS
This function converts the N_Vectors y and y_dot to simple double pointers, the user data f to a double and outputs the Jacobian supplied by eval_jacob to the CVODE jacobian jac Currently, CV_SUCCESS is always returned.
