Section: Random Number Generation
y = randnchi(n,mu)
where n is an array containing the degrees of freedom for
each generated random variable (with each element of n >= 1),
and mu is the non-centrality shift (must be positive).
n-1 degrees of freedom plus the square of a normal
deviate with mean mu and standard deviation 1.
