e05jlc (bnd_mcs_optget_real)

e05jlc is used to get the value of a real e05jbc optional parameter. e05jlc can be used before or after calling e05jbc, but the initialization function e05jac must have been called before calling e05jlc.

2 Specification

#include <nag.h>

void	e05jlc (const char optstr, double rvalue, Nag_E05State state, NagError fail)

The function may be called by the names: e05jlc or nag_glopt_bnd_mcs_optget_real.

3 Description

e05jlc obtains the current value of a real-valued optional parameter. For example

e05jlc ('Local Searches Tolerance', &loctol, &state, &fail);

will result in the value of the optional parameter

Local Searches Tolerance

being output in loctol.

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

None.

5 Arguments

1: $optstr$ – const char * Input: On entry: a string identifying a real-valued optional parameter (as described in Section 12 in e05jbc).
2: $rvalue$ – double * Output: On exit: if $fail . code =$ NE_NOERROR on exit, rvalue contains the real 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).
