How to keep count in a nested for loop?

Hi, I'm sure the answer is simple but I just can't figure it out. Let's say I have this code:

for i=1:3
  for j=1:3
    count=??;
  end
end
count

I want the result to be count=[1 2 3 4 5 6 7 8 9]

Thanks

There are many ways to do this. Here is one.

c = 0;
for i=1:3
  for j=1:3
    c=c+1;
  end
end

count = 1:c

Here is one way:

irange = 1:3;
jrange = 1:3;

for i=irange
  for j=jrange

    end
  end

count = 1:(numel(irange)*numel(jrange));
