The natural logarithm function in MATLAB is log not ln. [There are log10 and log2 functions for base 10 and base 2 respectively.]
From the questions you've been asking I suspect you're fairly new to MATLAB. If that's true, I have two suggestions.
- Take the roughly two hour free MATLAB Onramp tutorial (https://www.mathworks.com/support/learn-with-matlab-tutorials.html) to quickly learn the essentials of MATLAB.
- Make use of the documentation, searching for terms that are related to your task at hand. For example when I opened the documentation using the doc function and typed "logarithm" into the search bar log, log10, and log2 were each on the first page of the results.
