bi_zeros — SciPy v1.15.2 Manual (original) (raw)

scipy.special.

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)
