\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 = 
  <float>  - size: [1 9]
 
Columns 1 to 6
 2.01069760  0.18898647  0.74676013  2.37594628  8.25529575  1.80473185  
 
Columns 7 to 9
 0.22219571  2.26800203  1.96904421  

\end{verbatim}
