blocks|key|3926952|text|问题是，Matlab会分配每个轴的position属性，以便每个图周围都有空间。您可以调整position属性，也可以从文件交换中获取subaxis并以您喜欢的方式设置子图。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3926953|entityMap|0|LINK|mutability|MUTABLE|url|http://www.mathworks.com/matlabcentral/fileexchange/3696-subaxis-subplot^0|H|8|19|8|1V|7|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@$9|O|A|P|B|C]|$9|Q|A|R|B|C]]|D|@$9|S|A|T|1|U]]|E|$]]|$1|F|3|-4|5|6|7|V|8|@]|D|@]|E|$]]]|G|$H|$5|I|J|K|E|$L|M]]]]

The problem is that Matlab assigns the <code>position</code> property of each axis such that there is space around each plot. You can either adjust the <code>position</code> property, or you can get <a href="http://www.mathworks.com/matlabcentral/fileexchange/3696-subaxis-subplot">subaxis</a> from the File Exchange and set up the subplots the way you like.

Since MATLAB R2019b you can use <a href="https://www.mathworks.com/help/matlab/ref/tiledlayout.html" rel="nofollow noreferrer">tiledlayout</a> function to control the spacing of the subplots.

<hr>

Here's an example which shows how to obtain subplots without tile spacing:

<pre><code>figure
example_image = imread('cameraman.tif');
t = tiledlayout(5,3);
nexttile

for c= 1:15
 imagesc(example_image(:,c))
 if c &lt; 15
 nexttile
 end
end

t.TileSpacing = 'None';
</code></pre>

In addition to the other answers, you could try Chad Greene's <a href="https://au.mathworks.com/matlabcentral/fileexchange/52978-smplot-for-small-multiples" rel="nofollow noreferrer">smplot</a> from the FileExchange. This will produce a <a href="https://en.wikipedia.org/wiki/Small_multiple" rel="nofollow noreferrer">'small multiple'</a> plot and automatically deal with some of the hassle of Matlab's <code>position</code> property.
Example below showing default <code>subplot</code> behaviour, <code>smplot</code> with axis off and <code>smplot</code> with axis on, respectively:
<pre><code>image = randn(360*480,15);

% default subplot
figure;
for c=1:15
 subplot(5,3,c); 
 imagesc(reshape(image(:,c), 360,480)); 
 colormap gray; 
 axis image;
end
</code></pre>

figure;
for c=1:15
 smplot(5,3,c);
 imagesc(reshape(image(:,c), 360,480));

end
</code></pre>

<pre><code>% smplot axis on
figure;
for c=1:15
 smplot(5,3,c,'axis','on');
 imagesc(reshape(image(:,c), 360,480));

To minimize the white space surrounding each subplot, run: [1]
<pre><code>for c=1:15
 h_ax = subplot(5,3,c);
 % [...]

 outerpos = get(h_ax,'OuterPosition');
 ti = get(h_ax,'TightInset');
 left = outerpos(1) + ti(1);
 bottom = outerpos(2) + ti(2);
 ax_width = outerpos(3) - ti(1) - ti(3);
 ax_height = outerpos(4) - ti(2) - ti(4);
 set(h_ax,'Position',[left bottom ax_width ax_height]);
end
</code></pre>
This implementation automates the principle outlined in Jonas's answer.

I'm plotting 5 x 3 plots using subplot command, but there are massive margins around each subplot. 

How do I control the margin size around them?

<pre><code>figure;
for c=1:15
 subplot(5,3,c); 
 imagesc(reshape(image(:,c), 360,480)); 
 colormap gray; 
 axis image;
end
