Lambertw函数的导数

TīmeklisThe Lambert W-function, also called the omega function, is the inverse function of f(W)=We^W. (1) The plot above shows the function along the real axis. The principal value of the Lambert W-function is implemented in the Wolfram Language as ProductLog[z]. Different branches of the function are available in the Wolfram … Tīmeklis複素数 x の場合、方程式には無数の解 y = lambertW(k,x) があります。ここで、k は、すべての整数をその範囲とします。 すべての実数値が x ≥ 0 である場合、方程式には厳密に 1 つの実数解 y = lambertW(x) = lambertW(0,x) があります。

Tīmeklis2024. gada 13. apr. · The inverse produced by sympy is almost correct. The problem lies in the fact that the LambertW function has multiple branches over the domain (-1/e, 0). By default, it uses the upper branch, however for your problem you require the lower branch.
