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, `/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?
