scipy.interpolate.PPoly.integrate

PPoly.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, ‘periodic’, None}, optional

If bool, determines 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:

ig : array_like

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