使用MATLAB对离散信号进行运算，包括相加，位移，相乘以及变换等。(The use of MATLAB for computing discrete signals, including the add, shift, multiply and transform.)

一个自己用到的用matlab编写的fdtd源程序，感觉还可以。里面的参数没有设置，可以自己根据需要设置。(Used with its own written fdtd matlab source, feeling okay. Inside the parameter is not set up my own according to their needs.)

sin函数的简单一维小波变换与一维傅里叶变换的比较算法(sin function with a simple one-dimensional wavelet transform one-dimensional Fourier transform of the comparison algorithm)

模拟物理实验中的双缝干涉实验，输入波长 Lambda = 500nm，光缝距离的d = 2mm，光栅到屏幕距离z = 1m(Simulated physics experiments in the double-slit interference experiment input wavelength Lambda = 500 nm, the light slit distance d = 2mm, raster-to-screen distance z = 1m)

卫星通信信道链路参数计算与模拟.由于降雨对不同频段下的卫星通信造成不同的衰减，通过计算与模拟卫星通信信 道链路参数，可以设计出可靠性更高的卫星通信系统。(Satellite communication channel link parameter calculation and simulation. Due rainfall in different frequency bands for satellite communications under different attenuation caused by calculation and simulation of satellite communication channel link parameters, you can design a higher reliability of satellite communications systems.)

利用乘幂法求解矩阵A=[6，-11,6 1,0,0 0,1,0]的特征根（1,2,3）(solve the characteristic roots of array: A = [6,-11,6 1,0,0 0,1,0] by using matrix power method the root=(1,2,3))

基于电流滞环比较器的PMSM调速控制，通过对电流的滞环控制，达到控制转矩的目的。控制效果好！(PMSM speed control based on current hysteresis comparator, current hysteresis control, to achieve the purpose of the control torque. Control effect is good!)

说明：  计算在一个矩形里，用同等大小圆来覆盖这个区域，所需要的最小圆个数，我已经运行过(Calculated in a rectangle, the circle with the same size to cover the region, the minimum required for a round number, I have to run-off)

在数学建模培训中，降落伞问题很是突出，联系此题对同学有很大的提高，从而程序也很重要。所以发此文件。(Parachute Su snow modeling program title race body)

说明：  惯性导航系统中求解航向及姿态角的仿真程序，用matlab开发(Inertial navigation system to solve direction and attitude angle of the simulation program, developed by matlab)
