无约束多维极值问题,通过最小梯度搜索，求取最小值。-Unconstrained multi-dimensional extremum problem, by minimizing the gradient search, to strike a minimum.

模式搜索法，主要用于解决无约束多维极值问题。例如：飞机的精确定位。-Pattern search method, mainly used for to solve unconstrained multi-dimensional extremal problem. For example: the precise positioning of the aircraft.

这篇matlab程序是无需工具箱解决无约束目标函数最大值的程序(This matlab program is a program that does not need a toolbox to solve the maximum of an unconstrained objective function)
