LambertWIterIterative form of Lambert's w function for solving f(x) = x exp(x) for x |
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This function calculates an approximation of the inverse for
f(x) = y = x * exp( x )
within ∞ > y > -1/e. Please note, that for negative inputs two solutions exists. The function currently delivers the result x = -1 ... 0 for that particular range.
