scipy.interpolate.NdPPoly.
antiderivative#
- NdPPoly.antiderivative(nu)[source]#
- 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.
