An error status was returned by the program ‘xsetup’,
the X Window System version of ‘install’. The following
messages were written to standard error:

/home/leonardo/Azureus Downloads/Laboratoire Matriciel 2009 for Linux/update/install/main.sh: 178: /home/leonardo/Azureus Downloads/Laboratoire Matriciel 2009 for Linux/update/bin/glnx86/xsetup: Permission denied

Attempt to fix the problem and try again. If X is not available
or ‘xsetup’ cannot be made to work then try the terminal
version of ‘install’ using the command:

install* -t or INSTALL* -t

Para corrigir bastou acertar as permissões do arquivo xsetup.

Dentro do diretório de instalação do MATLAB, execute:

chmod 755 update/bin/glnx86/xsetup

E então, a instalação proseguiu corretamente.
