e05jac is used to initialize communication data for the suite of multi-level coordinate search functions: e05jbc, e05jcc, e05jdc, e05jec, e05jfc, e05jgc, e05jhc, e05jkc and e05jlc.

2 Specification

#include <nag.h>

void	e05jac (Integer n_r, Nag_E05State state, NagError fail)

The function may be called by the names: e05jac or nag_glopt_bnd_mcs_init.

3 Description

e05jac initializes the structure state for the solver e05jbc and the optional-argument handlers e05jcc, e05jdc, e05jec, e05jfc, e05jgc, e05jhc, e05jkc and e05jlc.

4 References

None.

5 Arguments

1: $n_r$ – Integer: This argument is no longer accessed by e05jac.
2: $state$ – Nag_E05State * Communication Structure: state contains information required by other functions in this suite. You must not modify it directly in any way.
3: $fail$ – 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.
