Generates a vector of non-central chi-square random variables with the given number of degrees of freedom and the given non-centrality parameters. The general syntax for its use is
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).
A non-central chi-square random variable is the sum of a chisquare
deviate with n-1 degrees of freedom plus the square of a normal
deviate with mean mu and standard deviation 1.
Here is an example of a non-central chi-square random variable:
--> randnchi(5*ones(1,9),0.3)
