Here is an overview of Matlab Mobile. Scroll to the bottom to System Requirements > Limitations to see a list of features not supported on Matlab Mobile. Your course may or may not require some of the features not supported in Matlab mobile.
If you need to write code for the course, I can't imagine doing so without a keyboard but that's just my opinion. If you have acces to university computers that you can use to write code, and if the code does not rely on any of the limitation for Matlab Mobile, perhaps you could develop code on the computer and then run it as needed from your phone using the cloud connection.
