# scipy.interpolate.NdPPoly.integrate¶

NdPPoly.integrate(ranges, extrapolate=None)[source]

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. ig : array_like Definite integral of the piecewise polynomial over [a[0], b[0]] x … x [a[ndim-1], b[ndim-1]]
