e05jfc may be used to supply individual integer optional parameters to e05jbc. The initialization function e05jac must have been called before calling e05jfc.

2 Specification

#include <nag.h>

void	e05jfc (const char optstr, Integer ivalue, Nag_E05State state, NagError *fail)

The function may be called by the names: e05jfc or nag_glopt_bnd_mcs_optset_int.

3 Description

e05jfc may be used to supply values for integer optional parameters to e05jbc. It is only necessary to call e05jfc for those arguments whose values are to be different from their default values. One call to e05jfc sets one argument value.

Each integer optional parameter is defined by a single character string in optstr and the corresponding value in ivalue. For example, the following allows the function evaluations limit to be defined:

nf = 1000;
e05jfc ('Function Evaluations Limit', nf, &state, &fail);

A complete list of optional parameters, their symbolic names and default values is given in Section 12 in e05jbc.

5 Arguments

1: $optstr$ – const char * Input: On entry: a string identifying an integer-valued optional parameter (as described in Section 12 in e05jbc).
2: $ivalue$ – Integer Input: On entry: an integer value associated with the optional parameter in optstr.
3: $state$ – Nag_E05State * Communication Structure: state contains information required by other functions in this suite. You must not modify it directly in any way.
4: $fail$ – NagError * Input/Output: The NAG error argument (see Section 7 in the Introduction to the NAG Library CL Interface).

6 Error Indicators and Warnings

NE_ALLOC_FAIL: Dynamic memory allocation failed.
See Section 3.1.2 in the Introduction to the NAG Library CL Interface for further information.
NE_BAD_PARAM: On entry, argument $〈value〉$ had an illegal value.
NE_INTERNAL_ERROR: An internal error has occurred in this function. Check the function call and any array sizes. If the call is correct then please contact NAG for assistance.
See Section 7.5 in the Introduction to the NAG Library CL Interface for further information.
NE_NO_LICENCE: Your licence key may have expired or may not have been installed correctly.
See Section 8 in the Introduction to the NAG Library CL Interface for further information.
NE_NOT_INIT: Initialization function e05jac has not been called.
NE_OPT_NOT_READ: The supplied optional parameter is invalid. A keyword or keyword combination was not recognized.
NE_OUT_OF_RANGE: Attempt to assign a non-positive value of $Function Evaluations Limit$ ( $nf$ ): $nf = 〈value〉$ .

Attempt to assign a non-positive value of $Local Searches Limit$ ( $loclim$ ): $loclim = 〈value〉$ .

Attempt to assign a non-positive value of $Static Limit$ ( $stclim$ ): $stclim = 〈value〉$ .
