scipy.special.y0_zeros(nt, complex=0)[source]

Compute nt zeros of Bessel function Y0(z), and derivative at each zero.

The derivatives are given by Y0’(z0) = -Y1(z0) at each zero z0.


nt : int

Number of zeros to return

complex : int, default 0

Set to 0 to return only the real zeros; set to 1 to return only the complex zeros with negative real part and positive imaginary part. Note that the complex conjugates of the latter are also zeros of the function, but are not returned by this routine.


z0n : ndarray

Location of nth zero of Y0(z)

y0pz0n : ndarray

Value of derivative Y0’(z0) for nth zero
