Initializes the current substream
distfun_streaminit ( I )
a 1-by-1 matrix of doubles, integer value, the type of action on the current stream. Available values are I=-1,0 or 1.
This function let us move forward or backward within the stream g.
distfun_streaminit(-1) :
sets the state of the current stream to its initial seed, i.e. reset it to the start of the substream.
distfun_streaminit(0) :
sets the state of the current stream to its previous seed, i.e. set it to the beginning of the current substream.
distfun_streaminit(1) :
sets the state of the current stream to the beginning of the next substream and resets the current substream parameters.
