Hi,
I need to include for loop in MATLAB to start with 2:13. But I need to start with 2,3,4 and skip 5 and again 6,7,8 and skip 9 and 10,11,12 until 13.
How can I implement this is for loop?
Many thanks in advance.

You can also use
ix = floor((4*(1:n)+2)/3);
where n is the desired length of the output.

for n = [2 3 4 6 7 8 13]
disp(n)
end

Yet another method:
idx = bsxfun(@plus,[1 2 3]',1:4:100)
for ii = idx(:)
disp(ii)
end

Yet another method:
idx = filter([1 1 1 1],[1 1 1 0],1:100)+1
