If you mean with the generators form matlab itself, then this is not 
possible. If you can replace the matlab generator then yes its possible 
with a purpose built mex file that mimics the Octave code. Check the thread

The code probably still works and probably still creates the same 
sequences as octave, but be careful of 32 versus 53 bit mantissas for 
the random numbers
