How can I insert my MATLAB figure (.fig) files into multiple subplots?

I have two MATLAB figure (.fig) files which I would like to insert into the subplots of a new figure.

In order to copy MATLAB figure (.fig) files into multiple subplots use the following commands:
h1 = openfig('test1.fig','reuse'); % open figure
ax1 = gca; % get handle to axes of figure
h2 = openfig('test2.fig','reuse');
ax2 = gca;
% test1.fig and test2.fig are the names of the figure files which you would % like to copy into multiple subplots
h3 = figure; %create new figure
s1 = subplot(2,1,1); %create and get handle to the subplot axes
s2 = subplot(2,1,2);
fig1 = get(ax1,'children'); %get handle to all the children in the figure
fig2 = get(ax2,'children');
copyobj(fig1,s1); %copy children to new parent axes i.e. the subplot axes
copyobj(fig2,s2);
For additional information on the COPYOBJ function, refer to the following documentation:
Attached are 2 scripts which will demonstrate how to place multiple FIG files into different subplots.
The file 'savfigs.m' creates 2 figures and saves them into the current working directory. Please run this file first.
The file 'copyaxes.m' opens these figures and then copies them to the different subplot axes.

Starting in R2019b, you can use tiledlayout to manage these axes.
openfig('fig1.fig');
ax1=gca;
openfig('fig2.fig')
ax2=gca;
figure;
tcl=tiledlayout(1,2);
ax1.Parent=tcl;
ax1.Layout.Tile=1;
ax2.Parent=tcl;
ax2.Layout.Tile=2;

For some reason, MATLAB may not be able to show the figure in short time. So, user had better add some time-delay after "ax = gac", or the subplot may repeat the same result.
if true
% code
end
ax = gca; pause(2)

This solution works very well. Labels, grid, graphs are all shown in the tiledlayout. Only the legend is missing. Any idea, how also the legend of the loaded figures appear in the tiledlayout?
