| nep | - the NEP context | |
| A | - Function matrix | |
| B | - preconditioner matrix (usually same as A) | |
| fun | - Function evaluation routine (if NULL then NEP retains any previously set value), see NEPFunctionFn for the calling sequence | |
| ctx | - [optional] user-defined context for private data for the Function evaluation routine (may be NULL) (if NULL then NEP retains any previously set value) |
