scipy.special.y0_zeros(nt, complex=False)[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.

Parameters:

Parameters:	nt : int Number of zeros to return complex : bool, default False Set to False to return only the real zeros; set to True 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.
Returns:	z0n : ndarray Location of nth zero of Y0(z) y0pz0n : ndarray Value of derivative Y0’(z0) for nth zero

nt : int

Number of zeros to return

complex : bool, default False

Set to False to return only the real zeros; set to True 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.

Returns:

z0n : ndarray

Location of nth zero of Y0(z)

y0pz0n : ndarray

Value of derivative Y0’(z0) for nth zero
