`scipy.interpolate._ppoly:real_roots`

Signature

def real_roots ( c , x , y , report_discont , extrapolate )

Summary

Compute real roots of a real-valued piecewise polynomial function.

Extended Summary

If a section of the piecewise polynomial is identically zero, the values (x[begin], nan) are appended to the root list.

If the piecewise polynomial is not continuous, and the sign changes across a breakpoint, the breakpoint is added to the root set if report_discont is True.

Parameters

c, x: Polynomial coefficients, as above
y : float: Find roots of pp(x) == y.
report_discont : bint, optional: Whether to report discontinuities across zero at breakpoints as roots
extrapolate : bint, optional: Whether to consider roots obtained by extrapolating based on first and last intervals.
