MATLAB codes used in Mathematical Methods for Diff

数值分析程序中的一个例子，matlab gui编程(Numerical analysis of an example program, matlab gui programming)

说明：  本人提交的用matlab的关于滤波器设计的作业，很有用的　(I used Matlab submitted on the design of filter operation, a very useful)

PCA算法。PCA的目的是找到能够分离出最大方差的方向，所以首先求原来所有数据三个维度上的协方差，然后求这个协方差的特征值，最大特征值为第一个方向，从此以此类推。(PCA algorithm. The purpose of PCA is to find able to isolate the direction of maximum variance, so first find all the data in three dimensions on the original covariance, and then find the eigenvalues ​ ​ of the covariance, the biggest feature is the first in one direction, from and so on.)

基于matlab仿真的四阶椭圆滤波器的仿真，其原理是基于切比雪夫滤波器的传递函数进行推导得来的(Matlab simulation based on fourth-order elliptic filter simulation, the principle is based on Chebyshev filter transfer function is derived come)

使用MATLAB的GUI接口设计一个简单的计算器，实现两个数的基本运算。(Use the GUI interface of MATLAB to design a simple calculator,realizing basic operations of two numbers.)

说明：  用于数字控制系统，采样根轨迹法分析，设计离散控制器(For digital control systems, sampling root locus analysis, design discrete controller)

说明：  电力系统中无刷直流电机的matlab软件仿真模型，对相关参数进行修改可以满足不同需求的直流电机仿真实验(Brushless DC motors in power system simulation model of the matlab software, to modify the relevant parameters to meet the different needs of the DC motor simulation)

This program in Matlab code simulates the wave propagation in a 1D dispersive medium by using FDTD method
