scipy.interpolate.NdPPoly.

antiderivative

NdPPoly.antiderivative(nu)

Construct a new piecewise polynomial representing the antiderivative.

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

Parameters:

nundim-tuple of int

Order of derivatives to evaluate for each dimension. If negative, the derivative is returned.

Returns:

ppPPoly

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.
