function

`scipy.interpolate._interpolate:PPoly.roots`

source: /scipy/interpolate/_interpolate.py :1167

Signature

def roots ( self , discontinuity = True , extrapolate = None )

Summary

Find real roots of 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.
