How do I merge 3 figures from 3 different programs in a single figure ?

I have 3 figures from 3 different codes and I want to merge all the 3 figures in a single figure.

I could merge 2 figures from 2 different codes using 'copyobj'.

But I'm unable to merge for 3 figures, I tried using the following code but I get an error.

f1 = figure;
my_work
f2 = figure;
shooting_method_scientific_rana_ode45
f3 = figure;
shooting_method_scientific_rana_ode45_2
copyobj(f3.Children.Children.Children, f2.Children, f1.Children)

I receive the following error

Error using copyobj
Too many input arguments.
Error in matching_result_3 (line 7)
copyobj(f3.Children.Children.Children, f2.Children, f1.Children

Is there a way to merge the 3 figures?

I also have attached the 3 m files here

Syntax for copyobj is two arguments, the handle (vector) of things to retrieve and the handle of the target.

I've no idea whether the syntax of f3.Children.Children.Children makes any sense at all or not, or whether that's somehow related to your having three figures, but presuming there is something that deeply nested, the (approximate) syntax would be something like

hFNew=figure;     % create the target
copyobj([f3.Children.Children.Children, f2.Children, f1.Children],hFnew)

Whether that would actually work will depend entirely on just what is in the three figures f1, f2, f3 and whether those above expressions actually return something or not.

I might have got the syntax of 'copyobj' wrong with

copyobj(f3.Children.Children.Children, f2.Children, f1.Children)

So, is there any other way to merge the three figures in a single figure by 'copyobj' or any other function.

As Answer shows, put the "from" handles in a vector as first argument, "to" as the second...
