poly5

mdhelper.fit.polynomial.poly5(x: ndarray, p1: float, p2: float, p3: float, p4: float, p5: float, p6: float) → ndarray

Convenience function for the poly5 model from MATLAB:

\[y=p_1x^5+p_2x^4+\cdots+p_6\]

Parameters:

xnumpy.ndarray

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

p1float

Coefficient \(p_1\) for the \(x^5\) term.

p2float

Coefficient \(p_2\) for the \(x^4\) term.

p3float

Coefficient \(p_3\) for the \(x^3\) term.

p4float

Coefficient \(p_4\) for the \(x^2\) term.

p5float

Coefficient \(p_5\) for the \(x\) term.

p6float

Constant term \(p_6\).

Returns:

fitnumpy.ndarray

Fitted \(y\)-values.
