1st question: yes

2nd question: the authors can add an explicit permission to link the
GPL'ed program they wrote against some proprietary library or program.

2nd question explored further: if said library or program is something
that is part of the proprietary system in question, then there's no need
to add an explicit permission. This is _not_ the case of MatLab.
