如何用Matlab构造不相等的宽度直方图? [英] How to construct unequal width histograms with Matlab?

问题描述

我想用不相等的bin(间隔)构造一个直方图..Matlab仅用相等的bin构造直方图，就好像它是一个图.. !!!

I would like to construct a histogram with unequal bins (intervals)..Matlab construct only histograms with equal bins as if it's a diagram..!!!

请帮助我...非常感谢！

Please help me...thanks a lot!!

推荐答案

下面是一个示例:

x = randn(100,1)*3;           %# some random data
e = [-10 -5 -3 -1 1 2 3 20];  %# edges of intervals:  e(i) <= x < end(i+1)
c = histc(x,e);               %# get count in each interval
bar(e, c, 'histc')            %# bar plot
set(gca, 'xlim',[e(1) e(end)])
