TīmeklisThe Lambert W function W (x) is a set of solutions of the equation x = W (x)eW (x). Solve this equation. The solution is the Lambert W function. syms x W eqn = x == … Tīmeklis2024. gada 28. dec. · Nₜ₊₁ = Nₜ exp[μ(1-Nₜ/K)] I would like to solve it the other way round: knowing Nₜ₊₁, I would like to estimate Nₜ. 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.

Tīmeklis1 Introduction The Lambert W(x) function is defined as the inverse function of yexpy = x, (1) the solution being given by y = W(x), (2) or shortly W(x)expW(x) = x. (3) Since the x 7!xexp x mapping is not injective, no unique inverse of the xexp x function exists. As can be seen in Fig.1, the Lambert function has two real branches with a branching 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 :

The indexing of the Lambert function W k ( z) is analogous to the branches of the logarithm log ( z) + 2 π i k, with k = 0 being the principal branches for both, and the positively-indexed branches being "stacked" on top of the principal branch, and similarly for the negatively-indexed ones. – J.
