Coding for nested loop problem

Question

0 个投票

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"

Just put an if condition in the nested loop with a

continue

statement in it.

Thank you very much Dear Adam.

Can you suggest any method to write the code for this without using for loops

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

Thank you very much
