.. function:: 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)).

|
|
.. function:: polyval(p: _ArrayLike, x: _ArrayLike) -> ulab.array
|
|
|
|
Evaluate the polynomial p at the points x. x must be an array.
