这是我们现代通信原理课程设计时所写的一个关于模拟信号的调频（FM）、双边带调幅（DSB）程序，里面还有详细的报告。(This is our modern communication principles course design of a written about analog signals (FM), the frequency modulation (DSB) with bilateral program, with detailed report.)

This code permit to simulate the sound received on microphones given their positions, the positions of the sound source(s), the frequency sampling of acquisition and the speed of sound. Assuming anechoical conditions.

产生LFM信号，纯LFM信号,雷达线性调频波，包括波形、频域分析等(LFM signal is generated, pure LFM signal)

基于MATLAB开发环境的图论中的最短路径模型(Graph Theory MATLAB development environment based on the shortest path model)

图象的消噪,图象的压缩,图象的融合,图象的增强(Image Denoising, image compression, image integration, enhanced image)

说明：  FEA 有限元计算matlab很早以前编制的程序，适应新的matlab环境。(FEA finite element matlab long ago programmed to adapt to the new matlab environment.)

此仿真是风力发电直流侧斩波控制simulink仿真(This simulation is the wind power dc side chopper control simulink simulation)

in this folder we simulate the system of lorenz, vanderpol

用matlab画了一个小动物，利用了plot，sina，cos等 函数(use Matlab drew a small animal )

关于蒙特卡洛法进行计算面积的，根据随机投点所得到的频率反推概率来求得面积。很好用的一种思维方法(About the Monte Carlo method to calculate the area, according to the random frequency of investment points to get the probability to obtain the inverse area. A good way of thinking with)
