2psk调制与解调，非常的有用，赶快下载。(2psk modulation and demodulation)

计算齿轮齿面接触强度和齿根弯曲强度安全系数（GB）(Calculate the safety factors of gear tooth contact strength and tooth root bending strength based on GB)

自己写的matlab源码，实现EMD分解，原始的EMD分解代码，简单实用。(Write their own Matlab source, EMD decomposition, the original EMD decomposition code, simple and practical.)

说明：  基于遗传算法的排课表的代码，通过调试，可以使用，如果想做成系统，请自行完成工程文件，这里只是排课的代码。(Time-table of the code, debugging, you can use if you want to create, please complete the project on its own, only here Course Scheduling code.)

时延下波束形成算法 matlab代码 欢迎下载(Time delay beamforming algorithm matlab code are welcome to download)

Function to generate a voice signal, adding noise, and filtering to recover the original signal.

matlab求最下的外接矩形的程序，很好用的，只要把图片名字改了就可以运行！(GOOD)

back probagation in neural network

在matlab中产生N(0,1)分布的白噪声(produced in Matlab N (0,1) and the white noise! !)

matlab程序将传递函数通过Z变换使其离散化，然后再把得到的脉冲传递函数改写成差分方程。便于接下来一步的C程序编程。(matlab program will transfer function Z-transform them through discrete, then put the resulting pulse transfer function of a differential equation rewritten. Facilitate the next step of the C programming.)
