"Unable to write to /usr/local/MATLAB/R2016b/. Please select a different folder."
This suggests you were on the right track. When you created the folder as root it is owned by root. You have several options IMO:
1. create a folder in your home directory if it is suitable for the software. Then you own the location. or 2. Change the ownership of MATLAB and lower levels to your user with the "chown" command. or (my recommendation with the given information) 3. Create a group called "matlab" and change group ownership using "chgrp" of the MATLAB directory.
The last option allows other users to use the software if you wish by joining the group.
