Tīmeklis2024. gada 27. nov. · The portion in red comes from the principal branch W 0 of the Lambert function, while the portion in magenta requires the branch W − 1 . The two solutions meet at x = e where. y = exp [− W (− 1 e)] = exp [− (− 1)] = e. on both of the branches involved. Another way to represent the nonobvious solution is via a … Tīmeklis4 Answers. Sorted by: 7. Let us consider the function. f ( x) = x log ( x) − a. Effcetively, the solution of f ( x) = 0 is given by. x = a W ( a) and, if I properly understood, you look for a computation method for getting W ( a). From definition W ( a) is defined such that a = W ( a) e W ( a) so Newton method seems to be (and is) very good.

TīmeklisEvaluating W(x) Because the inverse of the function f(x) = xe x cannot be expressed in terms of elementary functions, analysts use numerical algorithms to evaluate the Lambert W function at a value of x. The calculator above computes W(X) for any x value in the interval [-1/e, ∞). If x is within the sub interval (-1/e, 0), the calculator returns … TīmeklisLambert was one of the youngest witchers from Kaer Morhen and an adherent to the Wolf School.
