sum of array elements with specific condition?

조회 수: 4(최근 30일)
lets say I had A=[1 0 1 1 0 1 0 1 0 0 1 1 1 1]; then I want B(1)=sum of all A elements, B(2)= sum all elements of A from A(2) excluding a(1), similarly for B(3) = sum of all A elements with excluding A(1),A(2) and so on...then B should be B=[9 8 8 7 7 6 5 5 4 4 4 3 2 1] thanks

>> fliplr(cumsum(fliplr(A)))
ans =
9 8 8 7 6 6 5 5 4 4 4 3 2 1

This seems to be what you are after:
fliplr(cumsum(fliplr(A)))
ans =
9 8 8 7 6 6 5 5 4 4 4 3 2 1
5th digit is off. Could it be a mistake on your end?
