ulab.poly

ulab.poly.polyfit(y: _ArrayLike, degree: int) → ulab.array

ulab.poly.polyfit(x: _ArrayLike, y: _ArrayLike, degree: int) → ulab.array

Return a polynomial of given degree that approximates the function f(x)=y. If x is not supplied, it is the range(len(y)).

ulab.poly.polyval(p: _ArrayLike, x: _ArrayLike) → ulab.array

Evaluate the polynomial p at the points x. x must be an array.
