scipy.interpolate.BPoly.antiderivative¶

BPoly.antiderivative(nu=1)[source]¶

Construct a new piecewise polynomial representing the antiderivative.

Parameters:

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:	bp : BPoly Piecewise polynomial of order k + nu representing the antiderivative of this polynomial.

nu : int, optional

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

Returns:

bp : BPoly

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.
