This function flat the histogram of a specific window in image

一本较好的用MATLAB实现图像处理的书，有基础知识和实际例程(a better MATLAB image processing, and a basic knowledge of the actual routines)

在语音信号处理中，特征的聚类用matlab来实现(in voice signal processing, feature clustering to achieve using Matlab)

The mean hydration of carbohydrates as studied by normalized 2-D radial pair distributions, Claus A. Andersson and Sø ren B. Engelsen, Journal of Molecular Graphics and Modeling.The routine takes as input the location of the centerpoint of the two spheres and the two said spheres radii and calculates the rotational common volume used for normalizing the density maps of the atoms under investigation.

说明：  这是一个matlab的直方图均衡程序，先读入一副彩色图像，将其转成灰度图，输出该图的直方图，做均衡以后再次输出，可以看到均衡后图像直方图比较均匀了。(this is a histogram program based on matlab)

one spectral clustering algorithm for matlab
