图像傅里叶变换，matlab模拟成像过程的双缝干涉图形(Image Fu Liye transform, matlab simulation of the imaging process of double slit interference pattern)

说明：  该文档介绍了如何利用Mathematica的Mathlink通讯机制,混合多种高级语言编程.(This document describes how to use Mathematica' s Mathlink communication mechanism, mixed a variety of high-level language programming.)

matlab的s函数的编写教程，十分详细(matlab s function to write the tutorial, very detailed)

Particle in cell 方法的matlab代码，非常基础，算例是空间存在一带电平板情况下，等离子体的电场分布和离子密度分布。作为入门非常好。(Particle in cell method matlab code, very basic, there is a numerical example is charged under the flat space case, the electric field distribution of plasma and ion density distribution. As entry is very good.)

This code is filtering noise in image with median filter.

This model were build to simulate flicker when switches the big load to the network. The result show that, when switches the load, voltage and current fluctuate and make flicker.

基于matlab的直接序列扩频通信系统仿真，给出了扩频通信的整个流程(Simulation of direct sequence spread spectrum communication system based on MATLAB, the whole process of spread spectrum communication is given)

modulation function ask for matlab

利用发生机理进行语音 的合成，并且形成变速不变调和变调不变速的处理方法。(Use of the mechanism of occurrence of the synthesized speech, and forming a shift processing method does not change harmonizing shift.)
