You need to make the java files executable in order to install in Ubuntu 12.04.
Execute the commands: cd /sys/java/jre/glnxa64/jre/bin,
chmod +x java
This will make java executable. Other easier way is to navigate to the '/sys/java/jre/glnxa64/jre/bin' folder and right-click on 'java' file. Click 'Properties'. In the Permissions tab, check the box against 'Allow executing file as a program'.
Note: You cannot change the java permission if the installer files are located on a drive with NTFS file system. The files necessarily need to be on a drive with ext3 file system.
Now start the installation. Enjoy!

You have some problem with java. Try this one:
copy your Matlab Setup-files in a local drive like '/home/user/Desktop/Matlab':
install oracle-java: sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java8-installer sudo apt-get install oracle-java8-set-default
then: sudo ./install -javadir /usr/lib/jvm/java-8-oracle/
