scipy.special.bi_zeros#
- scipy.special.bi_zeros(nt)[source]#
Compute nt zeros and values of the Airy function Bi and its derivative.
Computes the first nt zeros, b, of the Airy function Bi(x); first nt zeros, b’, of the derivative of the Airy function Bi’(x); the corresponding values Bi(b’); and the corresponding values Bi’(b).
- Parameters
- ntint
Number of zeros to compute
- Returns
- bndarray
First nt zeros of Bi(x)
- bpndarray
First nt zeros of Bi’(x)
- bindarray
Values of Bi(x) evaluated at first nt zeros of Bi’(x)
- bipndarray
Values of Bi’(x) evaluated at first nt zeros of Bi(x)
