Odd numbered elements problem

I have problem about Matlab. There is one question about odd numbered elements. Can you help me to solve that my problem?

This is the question :

Write a function which every other element of the vector passed in. That is, it returns the all odd numbered elements, starting with the first.

Examples :

input x = [1 3 2 4 3 5]

output y is [1 2 3]

and

input x = [5 9 3 2 2 0 -1]

output y is [5 3 2 -1]

Thanks

function y = every0ther(x)
y = x(1:2:end);
end

Hope this helps!

you can probably use a loop

e.g. k=1; for n = 1:length(x), if mod(n,2)==1, y(k) = x(n); k =k+1; end; end

or

just build an odd index e.g. i = [ 1 3 5 7....]; then use x(i) to get your odd outputs.

there are many other ways, indexes and loops are all i can think of atm.
