background

清华张旭东老师《离散随机信号处理》教材第5章。本章首先简要复习经典谱估计的基本结论，然后分别讨论基于线性系统模型和复正弦模型的功率谱估计方法。(Qinghua Zhang Xudong teacher " discrete stochastic signal processing" textbook Chapter 5. This chapter begins with a brief review of the classical spectral estimation basic conclusion, and then discuss the power spectrum estimation based on linear system models and complex sinusoidal model approach.)

This script will attempt to find the band gaps in a phononic crystal by carrying out a Plane Wave Expansion of the various quantities using square array method. There are 2 programs, one for short and the other one is for acoustic long

平凹腔激光模式计算程序，利用边界元方法计算，matlab编程！(concave cavity laser mode procedures, the use of the boundary element method, the Matlab programming!)

矩阵卷积,matlab代码，希望能帮助那些需要进行运算的同学。。。(Matrix convolution)

matlab里面的一些简化工具包，便携易带，ncm工具包，还有一些教学演示程序(the matlab toolbox simple!please,if you want to show something,you can use it)

One program to simulation light passing through a glass sphere. It is interesting and can be used in geometric optics.

小波分析与信号处理 理论、应用及软件实现(Wavelet analysis and signal processing theory, applications and software)

convert binary data to gray data

it is a project based on invpwm in voltage regulator
