poly2

mdhelper.fit.polynomial.poly2(x: ndarray, p1: float, p2: float, p3: float) ndarray[source]

Convenience function for the poly2 model from MATLAB:

\[y=p_1x^2+p_2x+p_3\]
Parameters:
xnumpy.ndarray

One-dimensional array containing \(x\)-values.

p1float

Coefficient \(p_1\) for the \(x^2\) term.

p2float

Coefficient \(p_2\) for the \(x\) term.

p3float

Constant term \(p_3\).

Returns:
fitnumpy.ndarray

Fitted \(y\)-values.
