I have a problem with the MATLAB 2012 installation.

After having installed it using `Alt` + `F2` and having used

gksudo nautilus

I have installed MATLAB in the correct folder, which is:

/usr/local/MATLAB/R2012a

Then I inserted the license and the window told "activation complete" or something like that.

This made me happy, but only for a while because as soon as I try to search for MATLAB within the applications I cannot find it and neither if I try to run

matlab

into terminal it says:

command not found

How can I fix this problem?
