\section{DEG2RAD Convert From Degrees To Radians}

\subsection{Usage}

Converts the argument from degrees to radians.  The
syntax for its use is
\begin{verbatim}
   y = deg2rad(x)
\end{verbatim}
where \verb|x| is a numeric array.  Conversion is done by
simply multiplying \verb|x| by \verb|pi/180|.
\subsection{Example}

How many radians in a circle:
\begin{verbatim}
--> deg2rad(360) - 2*pi
ans = 
  <double>  - size: [1 1]
 0  

\end{verbatim}
