Hi,
I have A = (1:101). How can I extract every nth and (n+1)th element?
For example, if n = 10, I want reate B = [10, 11, 20, 21, ...100, 101].
I know how to extract every nth element using: A(1:n:end).
Any help would be appreciated! Thank you.

I'm not aware of any slick way to do this. I'd combine two arrays, one from 10:10:101, and one from 11:10:101.
n=10;
A = (1:101);
ind = sort([n:n:101 n+1:n:101]);
A(ind)
