how to add elements to an array in a for loop

Let's say there's an array sample= [ 2 4 5 6 3]
I want to make a function where we get the sum of all the elements greater than 5. so for this example it would be 5+6= 11.
I thought of doing a for loop to check if the elements are greater than 5, then create a new array with all the numbers which are greater than 5 and then use sum(sample). However, I'm not sure how make a new array.
for k= 1:numel(sample)
if samples(k) >=5
%need to make an a new array with all the elements greater than 5 from
%sample array
end
end

The MATLAB approach is to use logical indexing, not a loop:
V = [2,4,5,6,3];
N = sum(V(V>=5))
