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)
