Octave/Matlab - Subplotting figures with existing plots

My Octave workflow is the following:

I have tons of data to process, and lots of plots to generate. For each plot, I have a function that does all the work, generates its own plot and returns the handle of this plot for future modifications (if needed). Something like this:

function [h,p] = processData_and_generatePlot_A(datainput)
       %%.....
       h = figure();
       p = plot(h, ...)
       %%....
end

Now, what I'm trying to do is a script calling all this functions, collecting all the figures, and trying to combine all of them in only one figure (i.e., each plot generated should be a subplot in a new figure).

So, the questions are:

Thanks in advance

A method for merging plots in different figures as subplot of a new figure actually exists. What afraids me is that you have "lots of plots to generate", so you must define a criterion for splitting the existing plots into N figures in order to avoid cramming all of them into a single figure.

The aforementioned approach involves the usage of the copyobj function, and here is an example that you can easily modify following your needs:

f1 = figure();
x1 = -10:0.1:10;
y1 = sin(x1);
p1 = plot(x1,y1,'r');

f2 = figure();
x2 = -10:0.1:10;
y2 = cos(x2);
p2 = plot(x2,y2,'r');

pause(5);

f3 = figure();
sub1 = subplot(1,2,1);
sub2 = subplot(1,2,2);

copyobj(p1,sub1);
delete(f1);

copyobj(p2,sub2);
delete(f2);
