\section{RANDNF Generate Noncentral F-Distribution Random Variable}

\subsection{Usage}

Generates a vector of non-central F-distributed random variables
with the specified parameters.  The general syntax for its use is
\begin{verbatim}
   y = randnf(n,m,c)
\end{verbatim}
where \verb|n| is the number of degrees of freedom in the numerator,
and \verb|m| is the number of degrees of freedom in the denominator.
The vector \verb|c| determines the non-centrality shift of the numerator.
\subsection{Function Internals}

A non-central F-distributed random variable is the ratio of a
non-central chi-square random variable and a central chi-square random
variable, i.e.,
\[
   F_{n,m,c} = \frac{\chi_{n,c}^2/n}{\chi_m^2/m}.
\]
\subsection{Example}

Here we use the \verb|randf| to generate some non-central F-distributed
random variables:
\begin{verbatim}
--> randnf(5*ones(1,9),7,1.34)

ans = 

    2.0107    0.1890    0.7468    2.3759    8.2553    1.8047    0.2222    2.2680    1.9690 


\end{verbatim}
