I have a three layer nested for loop situation, I want to generate three figures in for loop "3" where each iteration of for loop "2" inserts subplots into each of the three and each iteration of for loop "1" generates its own set of three figures in for loop "3" to be populated with the subplots from loop "2".
I have code structured like this:
rawdata={'file1' 'file2' 'file3'};
field=[280 300 320];
vars=[1 2 3 4];
varst=[0,1,2,3];
varen=[2,3,4,5];
index=6;
for a=1:length(vars)
for b=1:index
linc(a)=(varen(a)-varst(a))/index;
xd=vars;
xd(b)=((b-1)*linc(b))+varst(b);
for c=1:length(field)
[data]=processing(rawdata{c});
[spec freq]=function(vars,field(c))
figure(c*a);
subplot(3,3,b);plot(freq,spec);
subplot(3,3,8);plot(freq,data);
end
end
end
This works except there are repeats of the figure index at certain combinations of a and c (for example: when a=2 and c=1, this overwrites the figure for a=1 and c=2.) I've tried a bunch of methods for getting around this but nothing has worked. Does anyone know how to do this?
Thanks!

counter = 1;
for ii = 1:5
for jj = 1:5
figure(counter)
%bla
counter = counter + 1;
end
end

I've tried that, it gives a new figure window for every subplot meaning "b" figures for every "a" iteration. I want only three figures for each iteration of "a", each having "b+1" subplots where the +1 is the data plot that stays unchanged for each "b" iteration. Each of the three figures correspond to one of the "field" values.
I can make the three data figures before the loops and add the subplots to them if the "a" index is 1. But if I want the "a" to be longer than 1, is there a way to duplicate the three figures, keep the old ones, and update the three new ones so that they correspond to the new "a" value and then fill in with the "b" iterations at that "a"? That might be faster too.

I'm sorry but I don't understand what you mean. Do you want to overwrite some of the figures only? You could explicitly store your figure and axes handles and just modify what you need when you need it:
fH = figure(1);
aH = subplot(3,3,9);
plot(aH, rand(10,2));
