Problem 44156. Weighted average
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
