Section: Random Number Generation
y = randnf(n,m,c)
where n is the number of degrees of freedom in the numerator,
and m is the number of degrees of freedom in the denominator.
The vector c determines the non-centrality shift of the numerator.
 
randf to generate some non-central F-distributed
random variables:
--> randnf(5*ones(1,9),7,1.34)
