lambert

In mathematics, the Lambert W function, also called the omega function or product logarithm, is a set of functions, namely the branches of the inverse relation of the function f(w) = w * eexp(w) where exp(w) is the exponential function and w is any complex number. In other words, the defining equation for W(z) is z = W(z) * exp(W(z)).
