mlfFminsearch

Minimize a function of several variables

Minimum number of arguments: six, maximum: user-defined. Terminate argument list with a NULL.

C Prototype

mxArray *mlfFminsearch(mxArray **fval, mxArray **exitflag,
                       mxArray **output, mxArray *funfcn,
                       mxArray *x0, mxArray *options, ...);

C Syntax

#include "matlab.h"

mxArray *exitflag = NULL;       /* Optional output argument(s) */
mxArray *output = NULL;         /* Optional output argument(s) */
mxArray *x = NULL;              /* Return value */

/* MATLAB syntax: x = fminsearch(fun,x0) */
