scipy.interpolate.ppform.antiderivative

ppform.antiderivative(nu=1)

Construct a new piecewise polynomial representing the antiderivative.

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

Parameters:

nu : int, optional

Order of antiderivative to evaluate. (Default: 1) 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.
