# scipy.interpolate.Akima1DInterpolator.integrate

`Akima1DInterpolator.``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 ouf-of-bounds points based on first and last intervals, or to return NaNs.
  Returns: | ig : array_like Definite integral of the piecewise polynomial over [a, b]
