Hello community,
I want for loops to check every element from 1 to n with all other elements. so letst say n=4
So I want to check Number 1 with 2,3 and 4// check number 2 with 3 and 4// and check number 3 with 4.
Can I build one or maybe two for loops for something like that?

Hey Scott,
so I ve got a matrix v = rand(n,2) and p = rand(n,2) .
for h =1:1000
p = p+v;
But if p(i,:) is in the near of p(j,:), they should switch the value of v. Now I will make an example for row i = 1 and i =4.
if norm(p(1,:)-p(4,:)) <= 2*r
v(1,:) = temp1
v(1,:) = v(4,:)
v(4,:) = temp1
end
end
And I know i want to verify the norm for every rows with all others. And then swaping the v of these rows, if the if statement is true. So I think I have to use two for loops, but I am not sure.
