Lambertw meaning in matlab
Tīmeklislambertw是朗伯W函数W = lambertw (X)表示为we^w=x;lambertw (x,k)表示多值函数的第K个分支，也就是说MATLAB把你的等式用这个表示函数表示了，并不算解出最终 … TīmeklisIn some corner cases, lambertw might currently fail to converge, or can end up on the wrong branch. Algorithm. Halley’s iteration is used to invert w * exp(w), using a first-order asymptotic approximation (O(log(w)) or O(w)) as the initial estimate. The definition, implementation and choice of branches is based on . References
