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))
