scipy.interpolate.BPoly.antiderivative#
- BPoly.antiderivative(nu=1)[source]#
Construct a new piecewise polynomial representing the antiderivative.
- Parameters
- nuint, optional
Order of antiderivative to evaluate. Default is 1, i.e., compute the first integral. If negative, the derivative is returned.
- Returns
- bpBPoly
Piecewise polynomial of order k + nu representing the antiderivative of this polynomial.
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.
