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));
