Lambert w function, also called ω function or logarithmic product function, is the inverse function of f (w) = w exp(w), where exp(w) is an exponential function and w is an arbitrary number. For any complex number z, there is z=w(z)*e*.
Nature:
Lambert w function cannot be expressed by elementary function. It has many uses in combinatorial mathematics, such as tree calculation. It can be used to solve many exponential equations, and it also appears in the solutions of some differential equations, such as.
Lambert w function has an important application in studying the actual model of solar cells.
Lambert w function is a special function. Also known as "ω function" or "product logarithmic function".
