Let's say I have a similiar loop to this one: ( This two loops are inside another one, but the issue isn't there )
for j = 1:length(path{i})
fprintf('%d ',path{i}(j))
for k = 1:length(dist_parc{i})
fprintf(' (%d) ', dist_parc{i}(k));
end
end
With this loop ( if j = 1:2 ) , what I'm trying to obtain is something like this -> numberfromJ (numberfromK) numberfromJ. But what I'm getting is -> numberfromJ (numberfromK) numberfromJ (numberfromK). So, after the second j loop I didn't want it to go back to k.
What I'm looking for is a way to loop the main one N times and the nested loop only N-1 times. Any way I can do this?

Cant be achieved like this?
for j = 1:5
for k = 1:j-1
[j,k]
end
end

for j = 1:N
% commands here are executed N times
if j < N
% commands here are executed N-1 times, for example a nested loop:
% for k = ...
% end
end
end
