How to Keep Nested For Loop Indexes From Equaling Each Other

If I have two nested for loops like this, is there a way to skip the iteration where i=j?

for i=1:50
    for j=1:50
        code
    end
end

Use the continue keyword.

for i=1:50
    for j=1:50
        if j==i
            continue; % breaks the inner for loop at the current iteration
        else
            % Do stuff here
            fprintf('i=%d, j=%d\n',i,j);
        end
    end
end

for i=1:50
    for j=1:50
        if j~=i
            ...
        end
    end
end

[Walter Roberson]

for i=1:50
  for j=[1:i-1,i+1:50]

or

for i=1:50
  for j=setdiff(1:50, i)

[per isakson]

for ii=1:50
    for jj=1:50
        if not(jj==ii)
            code
        end
    end
end
