Solving Lambert W Functions In MatLab®

Lambert W functions is a very specific topic of mathematics and you can find detailed information about Lambert w function through this link. Matlab® provides a very useful command to calculate the Lambert w functions which are called ‘lambertw()’. 

Here we explain how to use the ‘lambertw()’ command to calculate Lambert w for different variables in Matlab®. You can try the code in your Matlab® software. 

How To Use The ‘lambertw()’ Command In MatLab®?

Lambert w calculation has the equation like below. The value of ‘w’ is calculated in this function for the variables or values typed inside the parentheses of the ‘lambertw()’ command. 

The use of the ‘lambertw()’ command is very simple in Matlab®.

>> lambertw([1 5 pi])

ans =

    0.5671    1.3267    1.0737


In this example, we just typed the values inside the ‘lambertw()’ command then executed the code. You can see the results related to each value. You can enter symbolic variables and singular values inside the ‘lambertw()’ command.
