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

Can someone help me!?

Tanks in advance!
