for loop with exceptions

I wanted to run the loop

for even = 2:2:26

but I don't want to include 4. how do i say this?

Answer 1

[Pawel Jastrzebski]

loopCounter = [2,6:2:26]

for i = loopCounter
    i
    % your code
end

Answer 2

[Jan]

for even = 2:2:26
  if even ~= 4
    disp(even)
  end
end

Or

index = 2:2:26;
index(index == 4) = [];
for k = index
  disp(k);
end

Or for a larger list of excluded variables:

index = 2:2:26;
index = setdiff(index, [4,8,18]);
for k = index
  disp(k);
end
