说明：  Matlab数值计算，数据的统计描述和分析，参数估计，假设检验，Matlab统计工具箱的使用(Matlab numerical calculation, data analysis and statistical description, parameter estimation, hypothesis testing, Matlab Toolbox use statistics)

A band pass filter designed

This program simulates the minimization of a simple function with the simple coordinate search method.(Simple coordinate search algorithm)

说明：  Matlab Simulink仿真程序，主要完成了pv光伏阵列的搭建。(Matlab Simulink simulation program, mainly completed the PV array construction.)

说明：  使用Fisher 现行判别函数对给定的样本进行训练，对于两类，Fisher线性判别函数很好做，就是 w = Sw (m1 - m2), 其中：Sw为总类内离散度矩阵， m1, m2, 为两个模式类的均值(Fisher discriminant function using the current sample of a given training for two, Fisher linear discriminant function is well done, that is, w = Sw ' (m1- m2), where: Sw of the total within-class scatter matrices, m1, m2, the mean value for the two pattern class)

this file is very useful for student to calculate structures with MATLAB

将数据场和灰关联分析用到信号分选中，分选概率得到很大提高(The data fields and gray correlation analysis used in signal sorting, sorting greatly increase the probability)
