做一个特征提取的模拟。功能良好。非常实用(To make a feature extraction simulation. Good function. Very useful)

一般统计数据中有很多变量，采用组成分分析法，可以既有效抓住有效信息，又实现降维。本程序采用实例，来说明此方法。(General statistics, there are many variables, sub-components analysis, can only effectively capture useful information, but also to achieve dimensionality reduction. The program uses examples to illustrate this method. )

雷达系统的理论和设计一直占主导地位 概率论与统计，信息理论，信号处理和控制 然而，类似的编码译码的属性之间存在的视觉 BIAM和雷达已经黯然忽视的m所有雷达系统(For over six decades, the theory and design of radar systems have been dominated by probability theory and statistics, information theory, signal processing and control However, the similar encoding-decoding property that exists between the visual biam and radar has been sadly overlooked m all radar systems)

matlab 在led二次光学设计中的数值计算例程，不是原创，不过很有参考价值！(matlab numerical calculation routines, led the second optical design is not original, but a good reference value.)

Matlab教程第七章案例，面板数据分析、计量(Matlab Guide Chapter VII of the case, panel data analysis, measurement)

说明：  面包师图像置乱算法,可以图像进行置乱处理。(a method which can resort image)

CVSD（连续可变斜率增量调制）的编解码实现及调试。(CVSD realization, continuously variable slope delta modulator.)

SURF Features A frequent approach to feature extraction from images is SURF (Speeded Up Robust Features) Codebook You can use the function create_codebook.m to create a codebook with k-means Histograms Write a function that creates histograms of single images by assigning the image features to clusters from the codebook and counting their frequency Object recognition Choose two distinct subsets from the images. Create a codebook from one set

第12章 解线性方程组的迭代法.zip。是从书中光盘里直接拷贝的代码，放在这里，与大家共享，共同交流，希望对大家有帮助。(Chapter 12 solution of linear equations of the iterative method)

通过编程计算可得恢复后图像与原始图像的归一化均方误差为：(By programming available to restore the original image after the image and normalized mean square error:)
