fft

数值微分精度及步长的关系，截断误差和舍入误差，体会误差对结果的影响，用算法1 和算法2 分别得到的结果进行比较，由Taylor公式可得到两种算法的截断误差(Accuracy of numerical differentiation and the relationship between step length, truncation error and rounding error, the error on the results of experience with algorithm 1 and algorithm 2 respectively, to compare the results obtained by the Taylor formula for the truncation error of two algorithms available)

本书是介绍了基于MATLAB的系统分析与设计,主要介绍的是图像处理 .(This book is based on MATLAB for analysis and design, mainly to introduce the image processing.)

MATLAB GUI 实现摄像头拍照 保存 及对图片进行直方图均衡化处理，可以导入图片并对其进行处理并保存，整个程序完整设计。是初学入门的好例子。程序内置一张图片。压缩包中有编译成的可单独运行的exe文件。本程序开发环境是MATLAB2010b.(MATLAB GUI camera to save pictures and image histogram equalization processing, you can import the image and its processed and saved, the complete design of the entire program. Good example for beginners getting started. The program built-in picture. Compiled into a standalone exe file compressed package. MATLAB2010b the program development environment.)

图像处理，车牌识别，比较实用的参考程序。(Image processing, license plate recognition)

Sobel is a method of edge detection, matlab code

说明：  利用那个matlab进行图像处理的几个常用的.m文件，需要自己考进自己的处理目录就可以正常使用了。(Using the matlab image processing of several commonly used. M files, you need to test their processing into its own directory to be normal use.)

交叉验证源程序 评价模型性能的一种方式(cross validation)

L algorithme K nearest neighbor

说明：  基于PWM控制的无刷直流仿真，实验结果良好，具有很好的参考价值。(Based on the PWM control of Brushless DC simulation, the experimental results are good, has a good reference value.)
