I've been looking around for solutions to this and can't really seem to find a good answer so I thought I'd try this. I'm trying to install MATLAB 2013a on Saucy Salamander. I have all the files already downloaded and extracted to my Desktop. The installation files are for Linux 64 bit. This is what I'm doing and getting on the terminal (keep in mind I'm completely new to Linux and Ubuntu):

```
sudo ~/Desktop/matlab/install -v
[sudo] password:
sudo: /home/(myname)/Desktop/matlab/install: command not found
```

I tried doing things differently by moving the MATLAB folder to a different location (i.e. Downloads) and trying this:

```
cd ~/Downloads/matlab
sudo ./install
[sudo] password:
sudo: /home/(myname)/Downloads/matlab/install: command not found
```

If you guys know a better solution/what I'm doing wrong, please let me know.
