MATLAB:频率分布 [英] MATLAB : frequency distribution

问题描述

我在一个文本文件中有500个数值的原始观测值(范围从1到25000)，我希望在MATLAB中进行频率分布.我确实尝试了直方图(hist)，但是我更喜欢频率分布曲线，而不是块和条.

I have raw observations of 500 numeric values (ranging from 1 to 25000) in a text file, I wish to make a frequency distribution in MATLAB. I did try the histogram (hist), however I would prefer a frequency distribution curve than blocks and bars.

感谢您的帮助！

推荐答案

如果将两个输出参数传递给

If you pass two output parameters to HIST, you will get both the x-axis and y-axis values. Then you can plot the data as you like. For instance,

[counts, bins] = hist(mydata);
plot(bins, counts); %# get a line plot of the histogram
