In RcppBessel: Bessel Functions Rcpp Interface

The BesselJ Function

Description

Computes the Bessel function of the first kind for real or complex inputs.

Usage

bessel_j(z, nu, expon_scaled = FALSE, verbose = 0)

Arguments

z	A numeric or complex vector representing the input values at which to evaluate the Bessel function.
nu	A double representing the order of the Bessel function.
expon_scaled	A logical value indicating whether to use the exponentially scaled form of the Bessel 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 bessel_j function evaluated at the points in z.
