fracF

这是matlab 的一个工具包，里面包含了图像和视屏的工具(Piotr s Image & Video Matlab Toolbox， SketchTokens/toolbox/ should have channels, classify, filters, images, matlab)

说明：  单输入输出子空间moesp算法，可直接进行调用(Single-input-output subspace MOESP algorithm)

用Matlab实现现代功率谱估计，主要有Levinson法，Burg法，协方差法及修正协方差法，四种方法的结果放到一起进行比较，有详细的注释(Using Matlab implementation of modern power spectrum estimation, the main has Levinson Law, Burg method covariance method covariance method, and the amendment, four ways to put together the results of comparison, there is a detailed explanatory note)

说明：  ar模型预测，通过yule方法得到了ar系数，然后对一组随机数进行了预测。(The ar model predicts, through the yule methods ar coefficient predicted, then a set of random numbers.)

说明：  一、 简介 本仿真软件可以仿真波片对偏振光的相位调制过程。用户可以通过改变波片的类型，波片长轴与X轴的夹角，起偏器透光与X轴的夹角，检偏器透光轴与X轴的夹角等参数，来观察屏上光强及透过波片后的偏振光的信息。 建议在Matlab2008a或以上平台上运行本软件。 (I. Introduction The simulation software can simulate wave plate for polarization phase modulation process. Users can change the type of wave plate, wave plate angle between the long axis and the X-axis, from the transmission side device and the X-axis angle, the transmission axis of the polarizer angle between the X-axis parameters to the viewing screen glazing strong and polarized light through the wave plate information. Recommended Matlab2008a or run the software on the platform above.)

采用matlab语言编写的关于扩展有限元的程序，可以用于模拟裂缝的扩展。(the eXtended Finite Element Method )

灰色预测GM（1，N）代码，用于数学建模，提供残差等(Gray forecast GM (1, N) code for mathematical modeling residuals)

基于simulink的OFDM的仿真的例子，和大家分享(Based on the OFDM simulink simulation examples to share)
