- FitPoly( <List of Points>, <Degree of Polynomial> )
- Calculates the regression polynomial of degree n.
- Example:
FitPoly[{(-1, -1), (0, 1), (1, 1), (2, 5)}, 3]yields f(x) = x3 - 1 x2 + 1.
CAS Syntax
- FitPoly( <List of Points>, <Degree of Polynomial> )
- Calculates the regression polynomial of degree n.
- Example:
FitPoly[{(-1, -1), (0, 1), (1, 1), (2, 5)}, 3]yields x3 - x2 + 1.
Note:
- For order n there must be at least n + 1 Points in the list.
- See also FitExp Command, FitLog Command, FitPow Command and FitSin Command.
