鱼群算法，一种用Matlab实现的鱼群算法。(Fish algorithm, a Matlab algorithm to achieve the fish.)

此程序采用matlab语言进行编写，主要功能是根据数据画出研究生教材中数值分析的三次样条曲线(This program is written using matlab language, the main function is a cubic spline curve based on the data shown in numerical analysis textbook for graduate students)

里面包括matlab界面编程的一些基础知识 很有用 尤其对于初学者(Which includes some basic knowledge of Matlab programming interface is useful especially for beginners)

简单实用的模拟退火算法（SB/SW） 提供一个对理解模拟退火算法很好的程序示例(Simple and practical simulated annealing algorithm (SB/SW))

实现了定子磁链定向的DQ坐标系下的双馈电机模型(Stator flux oriented to achieve the DQ coordinate system doubly-fed machine model)

永磁同步电机矢量控制程序，位置与角度判断可通过霍尔位置传感器，编码器得到，其中也含有无位置传感器程序(Permanent magnet synchronous motor vector control program, to determine the position and angle through the Hall position sensors, encoders get, which also contains the program without position sensors)

黄金分割法求极小，返回值fm为函数极小值，tm为极小值点，f为给定函数，t为函数变量，[a,b]为变量t的搜索区间(Golden section method is extremely small, the return value for the function fm minimum, tm for the minimum point, f for a given function, t for the function of variables, [a, b] for variable search interval t)

本程序是关于预测函数的几个程序，包括阶跃输入以及在干扰情况下的系统影响，控制效果良好，自己可以其中的参数！(This procedure is about the predictive function of several procedures, including the step input, as well as the interference situation in the system under the impact of control works well, the parameters in which they can!)
