Well...

1. After installing matlab-support you should be able to Matlab from 
bash by typing the command

 >> matlab

Can you do that?

    a) if yes

        Can you evoke matlab-shell in Emacs? (M-x matlab-shell)

        Again, you should be able to do that after installing matlab-mode.

    b) if no:

        check what are the values of the variables: 
`matlab-shell-command` and `matlab-shell-command-switches`

        In my case they are equal: `matlab` and ("-nodesktop"), 
respectively, which is by default set in `matlab-shell.el` which is a 
part of matlab-mode package.

       Maybe you need to set them explicitely like here:
