sym.lambertw

Computes the Lambert W function of a symbolic expression.

Syntax

sym.lambertw(x)

Description

Computes the Lambert W function of a symbolic expression. The Lambert W function W(x) is defined as the inverse of f(w) = w*e^w. That is, if y = W(x), then y*e^y = x. This function returns the principal branch W₀(x).

Parameters

NameDescription
x- The argument (as a symbolic expression).

Returns
