Hi Surya,
I understand that you would like to get a trail license key for using and testing the MATLAB Mobile Application. I am pretty sure that you can run some basic commands such as plotting, array manipulation etc. in the application without the need of the license key. However, if you would like to get the trail license key for using any specific toolbox function. You can request for a trail version by filling the request form in the following link.
Hope this will help you!
