Returns a scaled version of array R such that the area across index I is 1.

Should the function Normalize be deprecated and eventually removed from Analytica? See the discussion tab and please weigh in with your opinions!

Declaration

Normalize( R : Numeric[I] ; I : Index )

or 

Normalize(R1,R2,I)

Notes

Normalize does not force the values along index I to sum to 1; to make the values sum to 1, use 

R/Sum(R,I).

Normalize does not cause the length of the resulting vector to be 1. To normalize in that sense, use: 

R / Sqrt(Sum(R^2,I))
