这是我自己写的对图像进行预处理的matlab源程序，主要是对图像进行光照补偿、旋转与尺度归一化。上传上来和大家一起学习、分享。(This is I wrote it myself pretreatment image matlab source, mainly for image illumination compensation, rotation and scale normalized. From up and study together, to share.)

用matlab编写的music程序，希望对大家有用(using Matlab music prepared by the procedures in the hope that it may be useful for )

白噪声是一种很典型的噪声，经常被用作噪声模型使用，因此，掌握白噪声的性质尤其其频谱，自身相关性很重要。( noise)

本程序根据训练好的网络文件ANN.mat预测新的数据文件，得到均方误差，并画出预测数据和原数据的对比图。(the procedures under the trained network file ANN.mat anticipating new data files, to be mean-square error. and the mapping out of the original forecast data and the map data comparison.)

GPS数据捕获matlab源代码，用于对接收到的GPS数据进行捕获运算。(GPS data capture matlab source code for the received GPS data capture operations.)

进行特征选择，利用权重进行特征选择，代码解释充分(Feature selection is carried out, feature selection is carried out with weight, and the code is fully interpreted.)

典型精馏塔的MATLAB模拟,(41块塔板，相对流率1.5，纯度99 ，液相流，恒压）(Typical dynamic model of distillation tower on MATLAB, (41 stages , relative volatility 1.5 99 purity liquid flow dynamics constant pressure))

按照给定的信号表达式，生成chirp信号，并计算信号的幅频和相频谱。(Expression in accordance with the given signal, to generate a chirp signal, and calculate the signal amplitude and phase spectrum.)

用Matlab编程，实现解决该问题的单样本训练BP网络，设置一个停止迭代的误差Emin和最大迭代次数。在调试过程中，通过不断调整隐层节点数，学习率η，找到收敛速度快且误差小的一组参数。产生均匀分布在区间[-4，4]的测试样本，输入建立的模型得到输出，与Hermit多项式的期望输出进行比较计算总误差（运行5次，取平均值）(Using Matlab programming, to solve the problem of single sample training BP network, set a stop error iterations Emin and the maximum number of iterations. In the debugging process, by continuously adjusting the hidden layer nodes, learning rate η, fast convergence and find a set of parameters small errors. Produce a uniform distribution in the interval [4,4] of the test sample, the model has been established input output with the expected output Hermit polynomial calculated by comparing the total error (run 5 times the average))
