scipy.interpolate.CubicHermiteSpline.
roots#
- CubicHermiteSpline.roots(discontinuity=True, extrapolate=None)[source]#
- Find real roots of the piecewise polynomial. - Parameters:
- discontinuitybool, optional
- Whether to report sign changes across discontinuities at breakpoints as roots. 
- extrapolate{bool, ‘periodic’, None}, optional
- If bool, determines whether to return roots from the polynomial extrapolated based on first and last intervals, ‘periodic’ works the same as False. If None (default), use self.extrapolate. 
 
- Returns:
- rootsndarray
- Roots of the polynomial(s). - If the PPoly object describes multiple polynomials, the return value is an object array whose each element is an ndarray containing the roots.
