`scipy.interpolate._interpolate:_PPoly.antiderivative`

source: build-install/usr/lib/python3.14/site-packages/scipy/interpolate/_interpolate.py:807

Signature

def antiderivative(self, nu = 1)

Summary

Construct a new piecewise polynomial representing the antiderivative.

Extended Summary

Antiderivative is also the indefinite integral of the function, and derivative is its inverse operation.

Parameters

nu : int, optional: Order of antiderivative to evaluate. Default is 1, i.e., compute the first integral. If negative, the derivative is returned.

Returns

pp : PPoly: Piecewise polynomial of order k2 = k + n representing the antiderivative of this polynomial.

Notes

The antiderivative returned by this function is continuous and continuously differentiable to order n-1, up to floating point rounding error.

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.
