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:i-1,i+1:50]
or
for i=1:50
for j=setdiff(1:50, i)

for ii=1:50
for jj=1:50
if not(jj==ii)
code
end
end
end
See i, Imaginary unit
