MATLAB: Only want last iteration displayed, whereas it continually sums up the array each loop

Question

x = [1 23 43 72 87 56 98 33]
summ = 0
for k = 1:length(x)
    summ = summ + x(k)
end

Answer 1

    x = [1 23 43 72 87 56 98 33] ;
    summ = 0 ;
    for k = 1:length(x)
        summ = summ + x(k) ;
    end
    fprintf('sum=%f\n',summ)

You can look into inbuilt function sum to get sum.

thesum = sum(x)
