用matlab编写的模数转换和数模转换的仿真程序，写的比较浅显，可以辅助看一看。(Modulus using matlab convert digital to analog conversion of the simulation program, written in relatively plain, can assist a look.)

Folding coefficient technique for DWT

The study documents the famous 3D engine for 3D developers learn to use.

介绍卡尔曼kalman滤波器原理的书籍，可以由此衍生出后来的相关性质(Introduced the principle of Kalman filter kalman and books, which was derived from the related properties)

利用模式理论，对给定几何尺寸以及折射率分布的光纤进行模式求解与绘图，该程序给出LP12模的求解与绘图。(the LP01 mode of the fiber)

its about image segmentation

很好很全的研究复杂网络的源代码，有matlab和vc两个版本的，挺实用的。(good source code of complex network。)

this code is used to show the result of power flow solution of a power system

冲击谱是振动冲击领域一个很重要的概念，该程序可以计算冲击谱(calculation of SRS)

实现了用burg法进行功率谱估计，并比较它的结果(Burg achieved by power spectrum estimation method, and compare its results)
