That check basically says to skip the first iteration of the loop. You could do this with an if statement and a continue statement, but rather than translate this strictly I'd probably instead just start the loop with k = 2.
% Strict translation with n = 5
for k = 1:5
if k == 1
continue
end
disp(k)
end
% Looser translation with n = 5
for k = 2:5
disp(k)
end
If n is less than 2 the loop over k won't do anything anyway, so starting at k = 2 doesn't cause any problems. Neither of the code examples below will display anything (other than the message that the loop is complete, since I wanted to prove to you that the code did in fact run.)
% Strict, n = 1
for k = 1:1
if k == 1
continue
end
disp(k)
end
disp('For loop #1 complete')
% Loose, n = 1
for k = 2:1
disp(k)
end
disp('For loop #2 complete')
