In wangtengyao/putils: Personal Utility Functions
lambertW R Documentation
The Lambert W function
Description
the Lambert W function is the inverse of f(x) = x*exp(x). The two main branches are b = 0 and b = -1.
Usage
lambertW(z, b = 0, maxiter = 10, eps = .Machine$double.eps, min.imag = 1e-09)
Arguments
z
a complex number
b
an integer, determining the branch of the W function
maxiter
maximum number of Halley iteration
eps
floating point tolerance
min.imag
floating point tolerance for imaginary part
Value
a real number of value log(a/(1-a))
