Tīmeklis1. Introduction . The Lambert W function, named after Johann Heinrich Lambert [1], is a standard function in both . Mathematica, where it’s called Product . Log x , and in Maple, where you can use both Lambert . W x or Lambert W0, x . The zero in this latter expression denotes the principal branch of the inverse of xex. The actual usage of the TīmeklisPlus généralement, la fonction W de Lambert permet de résoudre les équations de la forme : et avec et , x dans et . Il suffit pour cela de considérer une fonction tel que de répéter la démonstration ci-dessus et de considérer la formule de changement de base : . On obtient alors, avec : et avec :

This is in the form y = x exp(a(1−x/k)) From this post looks like the solution is not so straightforward since it requires to solve the Lambert function W, which involves complex numbers.
TīmeklisThe Lambert W function is the inverse of x --> x e^x, with two real branches, W0 for x >= -1/e and W-1 for -1/e <= x < 0 . Here the principal branch is called lambertWp, tho other one lambertWp, computed for real x . The value is calculated using an iteration that stems from applying Halley's method. This iteration is quite fast and accurate.
