sift

可以用于通信的信道编码，为FOUNTAIN码的原型码，非常实用，效果不错。(Can be used for communication, channel coding, the prototype code for the FOUNTAIN code, very useful, good results.)

周期图法功率谱估计仿真，通过改变窗函数类型、窗函数宽度、信噪比等参数，观察周期图法的性能(Periodogram power spectrum estimation )

L-system and IFS are used to the plant s simulation. In this package the theories of L-system and IFS were concisely described. The excellence and short of constructing Fractal image with L-system or IFS were discussed. So a method was put forward in this package. At last the three-dimension tree model ceatrs successfully based on L-system and IFS.

计算中间接轴在正弦激励下的动态特性，最大剪切应力、最大等效应力、弯曲应力等。(Axis in the calculation of indirect dynamic characteristics under sinusoidal excitation, the maximum shear stress, the maximum equivalent stress, bending stress and so on.)

主要介绍几种函数的傅里叶变换，及傅里叶函数变换的matlab实现(Several functions introduced Fourier transform, and the Fourier transform matlab realization function)

层次分析系统的算法，我找了很久才找到的，很不错(Analysis System-level algorithms, looking for a long time before I found very good)

平台（Matlab2008a，Simulink，Sysgen 10.1.03）硬件实现RGB2YCbCr (Platform (Matlab2008a, Simulink, Sysgen 10.1.03) hardware realise of RGB2YCbCr)

三角级数法模拟路面不平度的MATLAB命令流(The simulation method of Road roughness)

这是我做的第一个gui,实现的功能是画各种函数图形，给各位初学gui的参考下。(my frist gui)

说明：  光谱干涉条纹生成程序，有单色光和复色光的。(Spectral interference fringes generated program, a monochromatic light and polychromatic light of.)
