Provides a numerical tool for physicists needing the Lambert W function, but the approach is incremental.
The paper presents the Lambert W function and its numerical implementation in C++ for physics applications, using Halley's and Fritsch's iterations with various initial approximations.
The Lambert W(x) function and its possible applications in physics are presented. The actual numerical implementation in C++ consists of Halley's and Fritsch's iterations with initial approximations based on branch-point expansion, asymptotic series, rational fits, and continued-logarithm recursion.
