function

`scipy.interpolate._interpolate:NdPPoly.integrate_1d`

source: build-install/usr/lib/python3.14/site-packages/scipy/interpolate/_interpolate.py:2719

Signature

def integrate_1d(self, a, b, axis, extrapolate = None)

Summary

Compute NdPPoly representation for one dimensional definite integral.

Extended Summary

The result is a piecewise polynomial representing the integral:

p (y, z, ...) = \int_{a}^{b} d x p (x, y, z, ...)

where the dimension integrated over is specified with the axis parameter.

Parameters

a, b : float: Lower and upper bound for integration.
axis : int: Dimension over which to compute the 1-D integrals
extrapolate : bool, optional: Whether to extrapolate to out-of-bounds points based on first and last intervals, or to return NaNs.

Returns

ig : NdPPoly or array-like: Definite integral of the piecewise polynomial over [a, b]. If the polynomial was 1D, an array is returned, otherwise, an NdPPoly object.
