How to save same figure many times?

I'm trying to save a file for each iteration of the fgoalattain. I have it printing the figure each time just fine. But using the savefig function saves each iteration as the exact same name, which erases previous iterations figures. How do I generate a unique saved figure for each?

figure
%TEST diff 200, 100, 50 FOR TIMES
while diff > 200
    iterations = iterations +1;
    disp('running fgoalattain')
    xz = fgoalattain(obj_Func,xz,goal,weight,[],[],[],[],zeros(x3,x3),ones(x3,x3),[],Options);
    diff = sum(sum(abs(xz - a),2));
    pcolor(xz)
    drawnow

    savefig('iterpic.fig');
end

Simple: create unique filenames using a counter and sprintf

figure
%TEST diff 200, 100, 50 FOR TIMES
kk = 1; %//counter of files
while diff > 200
    iterations = iterations +1;
    disp('running fgoalattain')
    xz = fgoalattain(obj_Func,xz,goal,weight,[],[],[],[],zeros(x3,x3),ones(x3,x3),[],Options);
    diff = sum(sum(abs(xz - a),2));
    pcolor(xz)
    drawnow
    kk = kk+1;
    savefilename = sprintf('interpic%d.fig',kk); %//get filename
    savefig(savefilename);
end

sprintf generates a string based on the format specified, i.e. interpic%d.fig in this case. The %d is an argument to call a variable and represent it as an integer, which is after the comma, being kk in this case.

The argument to savefig is the file name, and since that's not changing, you're just overwriting the same file every time.

Try something like:

savefig(sprintf('interpic-%d.fig',iterations));

to append the iteration number to the file name.
