MATLAB程式设计与应用,包含常用的表达式的应用(MATLAB programming and application)

matlab C++混编程序，用C++处理数据，由matlab显示画图(matlab C++ mixed program, with C++ process the data displayed by the matlab drawing)

稀疏矩阵的matlab算法，以及稀疏矩阵存储技术的介绍。(Matlab sparse matrix algorithms, and sparse matrix storage technology introduction.)

说明：  高斯过程回归算法，根据已知数据预测未知数据，假设协方差函数，利用核函数计算(Gaussian process regression algorithm, predict unknown data according to known data, assume covariance function, and use kernel function to calculate)

本目录主要包括：文档和两个源代码。 其中一个源代码是识别程序的，另一个是一个矩阵类库的，书里面也使用过，所以一并附上。 因为已经保存了训练好的网络权值，所以第一次使用识别程序时，可以直接运行\Release目录下的可执行文件，然后对图片目录中的测试图片进行读入、识别。 当然读者也可以自行用训练样本训练网络，不过要特别注意训练样本的选择，否则可能造成识别率很低。训练样本选择的原则是，尽可能的有代表性，在训练时间不至于太长的情况下，训练样本数目尽量多。 (This directory includes: documentation and two source code. One of the source code is to identify the procedure, the other is a matrix class library, the book which is also used, so be attached. Have been saved because of the trained network weights, so the first use of identification procedures, he can run Release directory Under the executable file, then the test image directory read pictures, identification. Of course, readers are free to use the training samples to train the network, but pay special attention to training samples, otherwise it may result in knowledge Do not rate very low. Training sample selection principle is that as far as possible, representative, in the long training time Buzhi Yu s case, the training Training sample size as much as possible.)

时间序列中的自回归移动平均模型（ＡＲＭＡ），可以进行实时预测(A sequence of time regression moving average (ARMA) model, can real-time prediction)

一个比较经典的小游戏，通过matlab进行实现，较为简单(A classic game, matlab carried out through the realization of a relatively simple)

matlab进行通信仿真的时候，经常需要进行信噪比的计算，然后什么是真正的信噪比。本文给出了详细的解释。SNR(what is the really SNR )

美国建模大赛 gerrymand问题的源代码有注解 代码比较简单 使用模拟退火法求解(code with annotation of model of gerrymanding(MCM),the result is obtained by using annealing algorthm)

才用周期图法预测hurst指数。参数sequence为时间序列，isplot说明是否需要画图。(Have used the periodogram forecast hurst index. Parameter sequence for the time series, isplot explain the need for drawing.)
