此MATLAB程序实现函数的阶乘功能，经调试，完全正确(Procedures for implementation of this MATLAB function factorial function, with debug, completely correct)

MATLAB绘图教程~PPT格式~介绍各种基本绘图命令(MATLAB graphics tutorial ~ ~ PPT format introduce basic drawing commands)

matlab中CORDIC算法用来开方，在0~2之间精度很高(matlab CORDIC algorithm is used in prescribing between 0-2 high precision)

matlab程序，本程序为样本熵程序，程序可运行，是很好的特征提取参数.(matlab procedures, the procedures for sample entropy, the program can be run, is a good feature extraction parameters.)

This code demomstrates an improved algorithm based on the local binary fitting (LBF) model in Chunming Li et al s paper: "Minimization of Region-Scalable Fitting Energy for Image Segmentation", IEEE Trans. Image Processing, vol. 17 (10), pp.1940-1949, 2008. Usage: These codes can be used for Matlab 7.0.4 or higher versions in Windows. Run the Demos in the M-files for several test images. Once an image comes out, click the mouse to generate a polygon as the initial contour: left click to get a number of points, then right click to get the end point. The number of iterations may need to be increased if the initial contour is too far away from the desired object boundary.

ROI area identification, iteration, MCAA, zbthresh This program is simple, everyone can learn under
