在Matlab中保存直方图的频率数据

Question

I have two data set that been read from a txt file. I plot two histogram as picture below. How can i get and save the frequency data of this histogram? (i checked at the workspace, but no frequency values)

Note: X-Axis are values from txt file Y-Axis are the frequency

The coding of above histogram plot.

clear;
clc;

filename = 'DistanceValue1.txt';
filename1 = 'DistanceValue2.txt';
A = importdata(filename);
B = importdata(filename1);


h1 = histogram (A,50);
hold on
h2 = histogram (B,50);
hold off

Answer 1

histogram is a Matlab class for plotting data distributions. If you want access to the data use histcounts . Use

[n1, edges] = histcounts(A, 50);
[n2, edges] = histcounts(B, 50);

Answer 2

histogram对象在Values属性中包含其频率数据，可以通过以下方式访问该数据：

h1counts = h1.Values;
