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.

FREQ is defined in a more superior portion of the script. Here is the full script.

    fig = gcf;
    saveas(fig,'dddd.fig')

I suppose it would be quicker to store while running as well. I tried a few iterations ago but I had some trouble becuase of how the graphs are produced in sequence and not all at once.

Which line is showing the error?

PLOTNUM = PLOTNUM + 1;
filename =  "dddd" + PLOTNUM + ".fig";
fig = gcf;
save(fig, filename);

fig = gcf declaration makes it work correctly. Thanks!

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...).
