Matlab R2013a não inicia [RESOLVIDO]

Olá pessoal!

Estou com um problema no Matlab R2013a. Quando tento abri-lo pelo Unity aparece uma janela cheia de erros, como a seguir:
------------------------------------------------------------------------------------------------------

A instalação do Matlab encontra-se na pasta usr/local/MATLAB/MATLAB_Production_Server/R2013a/bin/matlab.

-------------------------------------------------------------------------------------------------------
O arquivo matlab.desktop é:

Aguardo ajuda!
Desde já obrigado!

So pra documentar,
tive um erro parecido com o 2016a e ubuntu 16.04
Depois de instalar, dei um:

sudo apt-get update

sudo apt-get install matlab-support

 

O matlab entao funcionou apenas com sudo. Dai eu tive que mudar as permissoes em meu ~/.matlab

chown -R $USER:$USER ~/.matlab
