How do I do a For Loop with two variables?

I want the loop to do for i=1:1:41 and for j=1:1:41, that is, the loop runs using i=1 and j=1, then i=2 and j=2 etc.
When I try the below nested function I get an infinite loop! for i=1:1:41 for j=1:1:41 Function end end
Can anyone help? Thanks!

@Helena: if i always equals j, why use two variables?

They're not the same, two different variables!

Then you dont need two for loops.
for i=1:41
j=i;
....do something
...
end
By the way, i and j are poor choice of variable names!

Now I'm getting the error 'Subscript indices must either be real positive integers or logicals.'
