| nep | - the NEP context | |
| A | - Jacobian matrix | |
| jac | - Jacobian evaluation routine (if NULL then NEP retains any previously set value), see NEPJacobianFn for the calling sequence | |
| ctx | - [optional] user-defined context for private data for the Jacobian evaluation routine (may be NULL) (if NULL then NEP retains any previously set value) |
