WeightedSum

The WeightedSum object adds two or more input values.  A set of dimensionless constants can be provided to multiply each input value prior to addition.

y = C1*x1 + C2*x2 + … + CN*xN, if the coefficients Ci are specified

  = x1 + x2 + … + xN        , if the coefficients Ci are not specified

where:

y = present output value for the weighted sum

xi = present value for the ith input to the weighted sum

Ci = ith entry in the CoefficientList input

N = number of inputs to the weighted sum

The value returned by the WeightedSum is calculated on demand.
