Problem 6. Select every other element of a vector
Write a function which returns 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]
Input x = [5 9 3 2 2 0 -1]
Output y is [5 3 2 -1]

Below is my code but it is failing the test 6 and 7. I tried inputting x=randi(100,10,1) and x=primes(20) in the scratchpad and the code works fine, outputing the right answer. There seems to be a problem with the evaluation of the answers.
function y = everyOther(x)
y = [];
for i = 1:2:length(x);
y(end+1) = x(i);
end

@Muhammad, take a deeper look at what the test cases are testing for.

y = x(1:2:end);
does the trick. :)
