introduction

Many experiments have been done and some experimental images have been obtained ,matlab Export saved for fig Format , Want to read multiple fig The picture is then combined into a big picture （ The form of subgraph ）, I checked some information , Record some of your thoughts and experiences .

1. Code

for i=1:10
	% The open fig Modify the path of the file as appropriate 
    hf(i)=open(['.\fig\sin-x1-test_',num2str(i),'.fig']);% open fig
    fig(i)=get(hf(i), 'CurrentAxes');% Get the drawn image 
end
% Create a new drawing window 
figure

for i=1:10
	% See how many rows and columns you want to draw, and change them as appropriate 
    subplot(2,5,i);% The first i Subtext 
    axChildren = get(fig(i),'Children');% Get the drawn image 
    copyobj(axChildren, gca);% Copy to the current window 
   close(hf(i));% Turn off the copied image 

    % Here's how to set the picture , Please amend... As appropriate 
    title(['S Curvilinear section ',num2str(i),' Secondary test ']);% Draw subgraph title 
    xlabel('Angle(\circ)');% Draw a subgraph x label 
    ylabel('Center WaveLength Change(nm)');% Draw a subgraph y label 
    yaxis([-0.05,0.2])% Draw a subgraph y The scope of the 
    xticks([0 20 40 60 80 100]);% Draw subgraph scale 
end

2. The final effect is as shown in the figure
