scipy.interpolate.BSpline.

antiderivative

BSpline.antiderivative(nu=1)

Return a B-spline representing the antiderivative.

Parameters:

nuint, optional

Antiderivative order. Default is 1.

Returns:

bBSpline object

A new instance representing the antiderivative.

Notes

If antiderivative is computed and self.extrapolate='periodic', it will be set to False for the returned instance. This is done because the antiderivative is no longer periodic and its correct evaluation outside of the initially given x interval is difficult.
