Can't install Matlab from ISO

Hello,

I have a Matlab R2013a disk image that I mounted using Furius ISO Mount (mount point: /home/andrew/Matlab801_MacUnix_iso). I ran the command

but I get "command not found." I also tried the method listed here <https://help.ubuntu.com/community/RootSudo> for dragging the install file into the terminal.

This started the installation process successfully, but when I tried to create a destination folder for Matlab I got the message "Unable to create destination folder /usr/local/MATLAB/R2013a". I thought this would have been fixed by running as sudo, but apparently not?

Thanks in advance.
