scipy.interpolate.PchipInterpolator.integrate

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

Compute a definite integral over a piecewise polynomial.

Parameters

afloat

Lower integration bound

bfloat

Upper integration bound

extrapolate{bool, ‘periodic’, None}, optional

Whether to extrapolate to out-of-bounds points based on first and last intervals, or to return NaNs. If ‘periodic’, periodic extrapolation is used. If None (default), use self.extrapolate.

Returns

array_like

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