Problem 44156. Weighted average

Created by Informaton in Community

Compute the weighted average Y, of the vector A, given the weight vector W.

The weighted average is the sum of the dot product of A and W, normalized by the sum of W.

Example 1:

A = [10 15 20 10];
W = [ 1  1  1  1];
Y = 13.75

Example 2:

A = [  10    15   20   10];
W = [0.25  0.25 0.25 0.25];
Y = 13.75

Example 3:

A = [10 15 20 10];
W = [ 2  4  4  2];
Y = 15
