# scipy.interpolate.NdPPoly.integrate

NdPPoly.integrate(ranges, extrapolate=None)

  Compute a definite integral over a piecewise polynomial.

  Parameters:
    ranges ndim-tuple of 2-tuples float

      Sequence of lower and upper bounds for each dimension, `[(a[0], b[0]), ..., (a[ndim-1], b[ndim-1])]`

    extrapolate bool, optional

      Whether to extrapolate to out-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[0], b[0]] x … x [a[ndim-1], b[ndim-1]]
