  • Can you copy/paste the results of typing java -version and gcc --version into a command prompt?

  • Matlab probably wants the Oracle JDK as opposed to the OpenJDK

This page states that, for Java, matlab requires two things, neither of which your system has:

  1. JDK 1.7 (You have 1.6)
  2. The Oracle JDK (you have the OpenJDK) (Note: It doesn't explicitly state this, but it links to the Oracle website)

You can fix both in one step by following the instructions in this askUbuntu answer

For gcc, it wants versoin 4.7 or higher. You have 4.6. See this askUbuntu answer on how to solve that.

I didn't ask for your gfortran version, and I'm unsure of how to get it. Verify that your gfortran is at least 4.7 as well.

  • Just edited it with regards to gcc; you'll need to update that as well
