【求助】x*exp(x)=2 这个方程怎么解？
 

[求助]急 急 急！ 各位大哥帮忙看看

x*exp(x)=2

这个方程怎么解？？


如果用matlab怎么解？？？
谢谢了

solve('x*exp(x)-2')
ans =
lambertw(2)
>> lambertw(2)
ans =
0.8526

非常谢谢
兄弟

lambertw
是什么意思？

LAMBERTW Lambert's W function.
W = LAMBERTW(X) is the solution to w*exp(w) = x.
W = LAMBERTW(K,X) is the K-th branch of this multi-valued function.
