如何将直方图保存到Matlab中的文件中?

问题描述

figure;
histogram = hist(np,180);
name=['histogram-' int2str(k) '.png'];
%% k is the iterator so basically I want to save all the images using a loop.
imwrite(out,name);

我得到的图像只是一条水平线.有人知道如何解决这个问题吗?

The image I got is only a horizontal line. Does someone know how to fix this?

推荐答案

您可以使用savefig代替imwrite

you can use savefig instead of imwrite

这是文档 http://www.mathworks.ch/ch/help/matlab/ref/savefig.html

savefig(h,filename)

h是图形的句柄.您可以跳过h保存当前图形.

h is the handle of figure. you could skip h to save the current figure.

(edit)savefig可能不存在，具体取决于MATLAB版本.在2012b中，它不会退出.

(edit) savefig may not be there depending on the MATLAB version. In 2012b, it does not exit.

所以 saveas 可能更好:

f=figure;
hist([1 2 2 3]);
saveas(f, 'histogram-1.png')

在MATALB 2012b中工作.您也可以将其另存为.fig.

This worked in MATALB 2012b. You can save it as .fig too.
