roots
(discontinuity=True, extrapolate=None)[source]¶ Find real roots of the the piecewise polynomial.
Parameters: - discontinuity : bool, 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: - roots : ndarray
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.
