示例1: myfunc_nlopt_gen
/// Objective function: calculates the objective value (ignore gradient calculation)
/// Keep track of how many times this function has been called, and report current
/// chi^2 (or other objective-function value) every 20 calls
/// Note that parameters n and grad are unused, but required by the NLopt interface.
double myfunc_nlopt_gen( unsigned n, const double *x, double *grad, void *my_func_data )

// following is a necessary kludge bcs theModel->GetFitStatistic() won't accept
// const double*
double *params = (double *)x;
double fitStatistic;
nlopt_result junk;
fitStatistic = theModel->GetFitStatistic(params);
// feedback to user
