Subplot in loop returns images in separate figures

Hello.

I am running this loop and I want to save the results after each loop and show them in the same subplot, but I get for example in this case 4 different figures with the corresponding image. I would like to get only one figure with the 4 subplots. Thanks for your help!

n=4;
nrows = n/2; % number of subplot rows f. subplot mit alle maskedRGBImage
ncols = n/2; % number of subplot columns
nsubs = nrows * ncols; % total number of subplots

for     f = 1:n
f4=figure('Name','Bilder vor und nach Bearbeitung');
hold(subplot(nrows, ncols,f), 'on');
subplot(nrows, ncols, f)
imshow(maskedRGBImage);
%this part shows the object idx on top of the object 
textFontSize2 = 8;	% Used to control size of "particle number" labels put atop the image.
labelShiftX = -140 ;	% Used to align the labels in the centers of the objects.
allBlobCentroids = [stats2.Centroid];
centroidsX = allBlobCentroids(1:2:end-1);
centroidsY = allBlobCentroids(2:2:end);
% Index in Mitte der Partikel anzeigen; top to bottom, left to right
for k = 1 : numberOfparticles          % Loop through all particles.
	text(centroidsX(k) + labelShiftX, centroidsY(k), num2str(k), 'FontSize', textFontSize2, 'FontWeight', 'Bold','Color','red');
end
%
title(['Masked Image' num2str(f)]);
drawnow;
end

f4=figure('Name','Bilder vor und nach Bearbeitung');

However, figure(f) and figure(n) are the only two syntaxes that return existing figures. When you pass in any parameter other than f (a figure handle) or n (an integer figure number) then it is either an error or else a new figure is created.

If you are trying to retrieve an existing figure, then record f4 before the for loop, and if necessary then

figure(f4)
