如何用轴子图将这个Matlab 2014代码重写为2016? [英] How to rewrite this Matlab 2014 code with axis-subplots to 2016?

问题描述

我为Matlab 2014编写的代码，但我想将其重写为Matlab 2016，以使其变得更加紧凑，因为它现在变得多余了

Code which I wrote for Matlab 2014 but which I want to rewrite it to Matlab 2016 such that it becomes more compact, since it is extranous now

hFig3=figure('Units', 'inches');
hax3_b1=axes('Parent', hFig3);
hax3_b2=axes('Parent', hFig3);
hax3_b3=axes('Parent', hFig3);
hax3_b4=axes('Parent', hFig3);

b1=subplot(2,2,1, hax3_b1); 
b2=subplot(2,2,2, hax3_b2); 
b3=subplot(2,2,3, hax3_b3); 
b4=subplot(2,2,4, hax3_b4);

% Example of common expression
set([b1 b2], 'Units', 'inches'); % http://stackoverflow.com/a/39817473/54964

u=0:0.1:1; y=sin(u); C = [0 2 4 6; 8 10 12 14; 16 18 20 22];
imagesc(b1, u, y, C); 
hold on; 
plot(b2, u'); 
histogram(b3, u');
histogram(b4, u);
hold off; 
drawnow; 

输出正常

操作系统:Debian 8.5 64位
MATLAB:2014，但希望转换为2016

OS: Debian 8.5 64 bit
MATLAB: 2014 but want to convert to 2016

推荐答案

您可以简单地编写:

figure('Units','inches');
b1 = subplot(2,2,1); 
b2 = subplot(2,2,2); 
b3 = subplot(2,2,3); 
b4 = subplot(2,2,4);

，或者，如果要具有轴数组，则最好:

or preferably, if you want to have an array of the axes:

figure('Units','inches');
b(1) = subplot(2,2,1);
b(2) = subplot(2,2,2);
b(3) = subplot(2,2,3);
b(4) = subplot(2,2,4);

或使用简单的for循环:

figure('Units','inches');
b(1:4) = axes;
for k = 1:numel(b)
    b(k) = subplot(2,2,k);
end

在任何选择的选项中，都不需要所有axes命令.

In any option you choose there is no need for all the axes commands.

这是您的所有演示"代码:

Here is all your 'demo' code:

b(1:4) = axes;
for k = 1:numel(b)
    b(k) = subplot(2,2,k);
end
set(b(1:2), 'Units', 'inches');
u=0:0.1:1; y=sin(u); C = [0 2 4 6; 8 10 12 14; 16 18 20 22];
imagesc(b(1), u, y, C); 
plot(b(2), u'); 
histogram(b(3), u');
histogram(b(4), u);

figure命令中可能也没有真正的需要，这取决于如何处理.

There might be no real need also in the figure command, it depends on what do with it.
