TīmeklisThe Lambert W(x) function is defined as the inverse function of yexpy = x, (1) the solution being given by y = W(x), (2) or shortly W(x)expW(x) = x. (3) Since the x 7!xexp x mapping is not injective, no unique inverse of the xexp x function exists. As can be seen in Fig.1, the Lambert function has two real branches with a branching Tīmeklis我们知道因为朗伯函数被定义为 xe^x 的反函数，于是乎 W(x) 也可以定义为 W(x)e^{W(x)}=x ，利用隐函数的求导法则，两边对 x 求导有： …

TīmeklisThe Lambert W function W (z) is defined as the inverse function of w * exp (w). In other words, the value of W (z) is such that z = W (z) * exp (W (z)) for any complex number z. The Lambert W function is a multivalued function with infinitely many branches. Each branch gives a separate solution of the equation z = w exp (w). … TīmeklisAlso, to anyone unfamiliar with the last step, it is one of the main identities of the Lambert W function. Now that we have the first derivative, we can simply differentiate as many times as we want to get all subsequent derivatives. The important thing to note, however, is that all subsequent derivatives will only require the W function to be ... laban 325 fountain pen
