airy_b {RcppBessel}R Documentation

The AiryB Function

Description

Computes the Airy function Bi for real or complex inputs.

Usage

airy_b(z, deriv = 0, expon_scaled = FALSE, verbose = 0)

Arguments

z

A numeric or complex vector representing the input values at which to evaluate the Airy function.

deriv

An integer indicating whether to compute the function (0 for the function itself) or its first derivative (1 for the first derivative). Defaults to 0.

expon_scaled

A logical value indicating whether to use the exponentially scaled form of the Airy function. Defaults to FALSE.

verbose

An integer specifying the verbosity level for error messages. Defaults to 0.

Value

A numeric or complex vector (depending on the input) containing the values of the airy_b function evaluated at the points in z.
