A simple function for drawing a circle on graph.

algorithm to find stock price wave when using positive return rate as wave condition.For example, find the S&P500 index whole waves, whose change rate is more than 5 from bottom to top.

structural problem finite element analysis

Compressive Sampling是最近讨论非常热烈的数据处理方法。用一个与变换基不相关的观测矩阵将变换所得到的高维信号投影到一个低维空间上，然后通过优化求解从这些少量的投影中以高概率重构出原信号。(Compressive Sampling is a very lively discussion of recent data processing method. A base with the transformation matrix will not change the relevant observation obtained a high-dimensional signal projected onto low-dimensional space, and then solved by optimizing the projection from these small reconstructed with high probability in the original signal.)

遗传算法求极值，matlabR2010b测试可以使用，对于刚刚开始研究算法的人是很好的程序(Genetic algorithms for extremes, matlabR2010b test can be used for people who have just begun to study the algorithm is a good program)

形成一个余弦调制波形，用于调制波形，具有非常重要的意义(Form a cosine wave modulation for modulation waveform, has great significance)

使用遗传算法对BP网络权值阈值进行优化，再用BP算法训练网络的代码，文本格式的(bp propoganda and genetic algorithm)

先进的pid控制 及其matlab的仿真 含源代码(Advanced pid control and matlab simulation with source code)

基于Kalman滤波算法的自适应AR模型，优点：算法收敛速度快；(Adaptive Kalman filtering algorithm based on AR model advantages: algorithm convergence speed )

说明：  给出了一个控制系统的模型，此模型采用ＭＡＴＬＡＢ模块搭建，解决跟踪问题(Gives a control system model, this model structures using MATLAB module to address the tracking problem)
