scipy.special.y1p_zeros¶
- scipy.special.y1p_zeros(nt, complex=False)[source]¶
Compute nt zeros of Bessel derivative Y1’(z), and value at each zero.
The values are given by Y1(z1) at each z1 where Y1’(z1)=0.
- Parameters
- ntint
Number of zeros to return
- complexbool, 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
- z1pnndarray
Location of nth zero of Y1’(z)
- y1z1pnndarray
Value of derivative Y1(z1) for nth zero
