Functions
static octave_value	do_rand (const octave_value_list &args, int nargin, const char *fcn, const std::string &distribution, bool additional_arg=false)
OCTAVE_EXPORT octave_value_list	Frand (const octave_value_list &args, int) you can restore the random number generator to the state ar
OCTAVE_EXPORT octave_value_list	Frandn (const octave_value_list &args, int) ode

Variables
static std::string	current_distribution = octave_rand::distribution ()
uses the	ite {Ziggurat Method for Generating Random Variables}
uses the	ospell {Marsaglia and Tsang} ``Ziggurat technique'' to transform from a uniform to a normal distribution. The class of the value returned can be controlled by a trailing code{"double"} or code{"single"} argument. These are the only valid classes. Reference: ospell{G. Marsaglia and W.W. Tsang}
