MATLAB: Is it possible to merge to graphs in one figure from two m files

bvp4cdifferential equationsgraphivpMATLABnumerical analysisodeode45plotshooting method

I have a code implementing shooting method to solve 4 ODEs

I have saved in two different files, one is by using solver 'bvp4c' and the other is by solver 'ode45'

Now is it possible to merge the two graphs in one figure each from these two m files

Yes, it is possible and there are many ways of doing it depending on the type of graphics object you have in the figure. Here is a sketch in which a line is copied from one axes to another using copyobj()

f1 = figure;
ax1 = axes(f1);
s1 = scatter(rand(1,100), rand(1,100));
f2 = figure;
ax2 = axes(f2);
l2 = plot(0:0.1:1, (0:0.1:1).^2);
copyobj(l2, ax1)

This will give you a general idea. To get a more concrete example, please share the type of graphic objects you have.

R2020a

close all
open('Deney 1_1.fig')
open('Deney 1_2.fig')
open('Deney 1_3.fig')
%

f1 = figure(1);
f2 = figure(2);
f3 = figure(3);
f4 = figure;
copyobj(f1.Children,f4);
copyobj(f2.Children,f4);
copyobj(f3.Children,f4);
ax_all = findobj(f4,'Type','axes');
f = figure;
tiledlayout(3,3)
for i =9:-1:1
nexttile   
ax_all(i).Position =get(gca,'Position');
end
close(f)

MATLAB: How to overlap plots from different scripts

Look up the documentation for copyobj.

Not only is a new figure generated with the code you shared but a very important error message is produced as well.

Error using copyobj
Figure parent must be the root.

What you want to do is copy the children of axis 1 to axis 2.

Assuming each figure has 1 and only 1 axis,

p1 = openfig("fig1.fig");
p2 = openfig("fig2.fig");
copyobj(get(gca(p1),'Children'), gca(p2));
%       ----------1------------  ----2---
% 1: children of axis in figure p1
% 2: axis of figure p2
