scipy.interpolate.PchipInterpolator.integrate

PchipInterpolator.integrate(a, b, extrapolate=None)

Compute a definite integral over a piecewise polynomial.

Parameters:

a : float

Lower integration bound

b : float

Upper integration bound

extrapolate : bool, optional

Whether to extrapolate to out-of-bounds points based on first and last intervals, or to return NaNs. Defaults to self.extrapolate.

Returns:

array_like

Definite integral of the piecewise polynomial over [a, b]
