MATLAB: Coding for nested loop problem

loopsMATLABnested loops

I want to run nested loop with two variables 'p' and 'q'
Outer loop is for 'p' and Inner loop is for 'q'
The problem is q should run for all values when ('q' not equal to 'p') and neglect the simulation of its contents when q=p
Is there any simple method to do this other than using "for loop"

Best Answer

for p = 1:10
    for q = 1:10
        if p ~= q
            ...
        end
    end
end
Without a for loop:
x     = rand(10, 10);
index = (1:10) ~= (1:10).';
mean(x(index))  % Mean of elements, which are not on main diagonal
