-
polyfit(
Float64List x, Float64List y, {CoeffMode mode = CoeffMode.scaled}) → Float64List -
Fits polynomial coefficients to
xandy, stores them in this instance, and returns the fitted coefficient vector. -
polyval(
Float64List x) → Float64List - Evaluates the coefficients stored by the most recent polyfit call.
-
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.

Static Methods
-
evaluate(
Float64List x, Float64List coeffs) → Float64List - Evaluates a polynomial in the original x-domain using Horner's method.
