Matlab绘制3-D图形的几个例子，很详细，也很全面的介绍了绘制3-D图形的函数，其中最后一个是画直方图的，横向和纵向都有例子。-Matlab 3-D graphics to draw a few examples of very detailed and very comprehensive introduction to drawing 3-D graphics functions, the last one is the histogram drawing, horizontal and

计算和匹配图像的三维直方图,h=getPatchHist(img,weight,nbins),nbins为每一个通道上bin的个数，如[8 8 8] -caculate and match the 3d histogram of an image

基于3维直方图的聚类分割,对初学matlab的同学非常有用的哈！-3-D histogram clustering based segmentation matlab beginner students of very useful Ha!
