这是一份关于matlab曲线拟合的文章，供大家学习~~180K(This is an article on the matlab curve fitting for them to learn ~ ~ 180K)

拟牛顿法matlab程序，是使用拟牛顿法解决优化问题的基础程序(Quasi-Newton method is one of the most effective Methods for solving nonlinear optimization problems)

采用模糊PID控制进行阶跃响应，在第300个采样时间控制器输出加1.0的干扰。(The fuzzy PID control of the step response, in the first 300 sampling time the controller output increases 1.0 interference.)

本程序可以进行主层分分析，将因素在轴上进行投影，选择几个贡献率比较大因子(This procedure can be the main floor sub-analysis, factor in the axis for projection, choose the contribution rate of a few relatively large factor)
