时钟仿真程序，可实现多种显示方式 包括12/24小时制、是否显示秒数(clock simulation program can achieve a variety of formats, including 12/24 hours System, which is shown in seconds)

计算光子晶体光纤的有效折射率程序，可以得到有效折射率随波长变化图(Calculate the effective refractive index of the photonic crystal fiber program, you can get change in the effective refractive index with wavelength)

Matlab教程PPT，Matlab概述与应用程序基础(Matlab PPT)

说明：  Matlab 常用图像函数（强大，实用），上传的还是一些matlab的东西,别人给的,应该是一些图象处理比较有用的东西。(Matlab image function (strong, used the practical), upload or some Matlab thing, other people to give, and there should be some image processing is useful things.)

用matlab实现混沌理论中的相空间重构代码，很好用的工具！(Chaos theory in phase space reconstruction using matlab code, very easy to use tool!)

numerical filter, Matlab, in Romanian

比较最佳平方逼近二次多项式，Chebyshev截断级数法以及插值余项极小法这三种函数逼近方法，并给出图形(Comparison of the best square quadratic polynomial approximation, Chebyshev truncated series method as well as more than a very small interpolation method of the three function approximation methods, and gives graphical)

说明：  实现4psk调制的源程序，以及对应的在白噪声信道下的系统性能(achieve 4psk modulation source, as well as corresponding white noise in the channel system performance)
