nag_opt_nlp_option_set_double (e04whc) may be used to supply individual double optional parameters to
nag_opt_nlp_solve (e04wdc). The initialization function
nag_opt_nlp_init (e04wcc) must have been called before calling
nag_opt_nlp_option_set_double (e04whc).
nag_opt_nlp_option_set_double (e04whc) may be used to supply values for double optional parameters to
nag_opt_nlp_solve (e04wdc). It is only necessary to call
nag_opt_nlp_option_set_double (e04whc) for those arguments whose values are to be different from their default values. One call to
nag_opt_nlp_option_set_double (e04whc) sets one argument value.
Each double optional parameter is defined by a single character string in
string and the corresponding value in
rvalue. For example the following illustrates how the
stability tolerance could be defined:
factol = 100.0;
if (illcon) factol = 5.0;
e04whc ("LU Factor Tolerance", factol, &state, &fail);
Optional parameter settings are preserved following a call to
nag_opt_nlp_solve (e04wdc) and so the keyword
is provided to allow you to reset all the optional parameters to their default values before a subsequent call to
nag_opt_nlp_solve (e04wdc).
A complete list of optional parameters, their abbreviations, synonyms and default values is given in
Section 12 in
nag_opt_nlp_solve (e04wdc).
