对常用的MATLAB程序函数进行了归纳总结，简单易查，使用方便。(MATLAB program commonly used functions are summarized, simple and easy to search, easy to use.)

现代图像处理技术及Matlab实现，介绍了一些matlab用法(modern image processing technology and Matlab, introduced the use of Matlab)

双向渐进结构拓扑优化原始代码，采用软杀伤法的BESO( the source code of Bidirectional evolutionary structural topology optimization with the soft kill law BESO)

企业文件，不错的，大家试下载下来玩玩，好像还有论坛功能的，这个是最新版本。.. (Corporate documents, well, we try to download it to play, as if there are features of the forum, this is the latest version. ..)

RNNSIM ver. 1.0 is a program with an intercative graphical user interface (GUI) that runs under MATLAB ver. 5.0 or higher. The program can be used in training and testing the Random Neural Network(RNN) models. This version (ver. 1.0) implements only the 3 layer feed forward RNN model. In the next versions, the multi hidden layers and the recurrent RNN models can be implemented. To obtain faster training, the training section can be written as a MEX file and invoked from the GUI. If you have the m files in the directory rnnsim for example, then you can run the program following the next steps: 1- run MATLAB as usual 2- from the MATLAB command window, write cd rnnsim 3- from the MATLAB command window, write rnnsim

一个非常简易的均线策略，仅作展示用，高手绕行。 5日均线上穿20日均线，做多1手；5日均线下穿20日均线，做空1手； 其中这里上穿、下穿如下定义： 上穿定义：MA5当天大于MA20，前一天MA5位于MA20之下 下穿定义：MA5当天小于于MA20，前一天MA5位于MA20之上 测试数据：IF1112 （2011/5/3-2011/12/8）每日收盘价。 初始资金 50万(a sample back testing matlab code based on ma)
