- scipy.special.y1_zeros(nt, complex=False)¶
Compute nt zeros of Bessel function Y1(z), and derivative at each zero.
The derivatives are given by Y1’(z1) = Y0(z1) at each zero z1.
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.
z1n : ndarray
Location of nth zero of Y1(z)
y1pz1n : ndarray
Value of derivative Y1’(z1) for nth zero
