- Normalize( <List of Numbers> )
- Returns a list containing the normalized form of the given numbers.
- Example:
Normalize({1, 2, 3, 4, 5})returns {0, 0.25, 0.5, 0.75, 1}.
- Normalize( <List of Points> )
- Returns a list containing the normalized form of the given points.
- Example:
Normalize({(1,5), (2,4), (3,3), (4,2), (5,1)})returns {(0,1), (0.25,0.75), (0.5,0.5), (0.75,0.25), (1,0)}.
Notes:
- If you are doing calculations using big or small numbers (eg using FitGrowth) then normalizing them might avoid rounding/overflow errors
- This command is not applicable to 3D points.
- The operation of normalization maps a value x to the interval [0, 1] using the linear function x \mapsto \frac{x-Min[list]}{Max[list]-Min[list]}.
