感知器算法的基本思想是，对初始的或迭代中的增广权矢量 ，用已知的训练模式检验它的合理性，当不合理时，对其进行校正，校正方法实际上是最优化技术中的梯度下降法，上传的是用matlab解决感知器问题。(The Perceptron Algorithm The basic idea augmented weight vector of the initial iteration, the known training mode to test it reasonable, unreasonable, its correction, the correction method is actually the most optimization techniques the gradient descent method, upload matlab to solve perception problems.)

相关分析过程的matlab方法，采用累计贡献率的方法，混沌的判断指标Lyapunov指数计算。( Correlation analysis process matlab method, The method of cumulative contribution rate Chaos indicator for Lyapunov index calculation.)

一个马尔可夫（MRF）图像分割MATLAB的源码,有30几个函数。Markov随机场的例子程序,对于初学入门MRF的人很有用,能得到直观的印象。(A Markov (MRF) image segmentation MATLAB source code, 30 a few functions. Markov random sample program, for beginners who are useful entry-MRF can get a visual impression.)

说明：  5、绘制散点图。 对发射和接收信号利用scatterplot函数可显示信号星座图的样子及噪声对信号造成的失真程度。在该图中，横轴代表了信号的同相分量而纵轴代表了正交分量。下面的代码还利用了 对接收信号利用modem.deqammod对象的demodulate方法进行解调。解调结果为包含0到15之间整数的列向量。 (5, draw a scatter plot. The transmitted and received signals can be displayed using a function of the degree of distortion scatterplot like and noise signals caused by the signal constellation of FIG. In this figure, the horizontal axis represents the in-phase component signal and the vertical axis represents the quadrature component. The following code is also used to demodulate the received signal using the method of demodulating modem.deqammod object. Demodulation result is an integer from 0 to 15 comprising a column vector.)

此为模拟台球动态击球的MATLAB源代码，描述了一个球在桌面某一位置击中另一个球的动态过程。很好的代码，值得学习！(This is a dynamic simulation of billiard ball MATLAB source code, describes the location of a ball hit another ball the desktop of a dynamic process. Good code, it is worth learning!)

Pseudo-Random Generator(Autokorelation function of PN secvence)

这是一个LZW解压的matlab子函数程序和主函数，要结合我第一个上传的LZW压缩来看，这样有助于理解，效果很少明显，压缩率80 以上，不懂的跟我联系，我交你！！！我弄懂了！(It is a realisation of lzw decompression.Its compression ratio is beyond 80 .Its compression source is the first file which I have uploaded.If you have some questions,you can contact with me.)

用于地球物理中重力和磁力位场边界提取的几个常用的算法，包含数据处理，建模，和滤波。(Gravity and Magnetic Data Mapping, Processing, Modeling and Filtering Software.)
