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))

N = 11
