Fonction bi_zeros - module scipy.special

Signature de la fonction bi_zeros

def bi_zeros(nt) 

Description

bi_zeros.__doc__

    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
    ----------
    nt : int
        Number of zeros to compute

    Returns
    -------
    b : ndarray
        First `nt` zeros of Bi(x)
    bp : ndarray
        First `nt` zeros of Bi'(x)
    bi : ndarray
        Values of Bi(x) evaluated at first `nt` zeros of Bi'(x)
    bip : ndarray
        Values of Bi'(x) evaluated at first `nt` zeros of Bi(x)

    Examples
    --------
    >>> from scipy import special
    >>> b, bp, bi, bip = special.bi_zeros(3)
    >>> b
    array([-1.17371322, -3.2710933 , -4.83073784])
    >>> bp
    array([-2.29443968, -4.07315509, -5.51239573])
    >>> bi
    array([-0.45494438,  0.39652284, -0.36796916])
    >>> bip
    array([ 0.60195789, -0.76031014,  0.83699101])
