Having trouble with saving multiple figures as they are produced in sequence.

Hello. I'm currently having some trouble saving some figures that my script is producing from a pool of pre-collected data. Really I just need the figures in a .fig format so I can inspect them and obtain the data points in a seperate script. My script currently reads:
cycle=[200 80 40 20];
begin=[753 785 795 739];
cnum=[2 4 8 16];
for i=1:4:16
ii=(i-1)/4+1;
subplot(2,2,ii)
for j=0:3
k=i+j;
for ll=1:cnum(FREQ)
tempsin=sintrace(begin(FREQ)+cycle(FREQ)*(ll-1):begin(FREQ)+cycle(FREQ)*ll-1,k);
sinpart(1:cycle(FREQ),ll)=tempsin;
end
clear tempsin;
tempsum=sum(sinpart,2)/cnum(FREQ);
sinavg(1:cycle(FREQ),k)=tempsum;
clear tempsum sinpart;
plot(vsine(begin(FREQ):begin(FREQ)+cycle(FREQ)-1,k),sinavg(1:cycle(FREQ),k))
hold on
end
hold off
title([num2str(freq(FREQ)),'Hz, ','Mean V=',num2str(vmean(ii)),'V'])
axis([-100 100 -1.5 1.5,])
end
pause
plot(vsine(begin(FREQ):begin(FREQ)+cycle(FREQ)-1,k),sinavg(1:cycle(FREQ),k))
fig = gcf;
saveas(fig,'dddd.fig')
With my attempt at saving the figures at the bottom. l honestly feel as though there is a very simple way of going about this that I just havent considered yet.

Which line is showing the error?
PLOTNUM = PLOTNUM + 1;
filename = "dddd" + PLOTNUM + ".fig";
fig = gcf;
save(fig, filename);

You don't mention the problem, but I will say that I typically put a
drawnow
command just before saving/printing figures. I'm not sure why, but I have found that MATLAB sporadically gets confused about which figure is being saved. Using drawnow, and specifying the figure in the saveas command (as you have already done) generally works for me.

This works to save one of my figures (usually the last one produced), but since the figures are produced in sequence and not all at once, I need a path to save all of the average graphs in sequence as they are produced to seperate .fig files. It would also help if I could find a way to save the plot points of the average graphs as they are produced. I guess it would something like (sin100average.fig, sin250average.fig, sin500average.fig, etc...).
