\section{EPS Double Precision Floating Point Relative Machine Precision Epsilon}

\subsection{Usage}

Returns \verb|eps|, which quantifies the relative machine precision
of floating point numbers (a machine specific quantity).  The syntax
for \verb|eps| is:
\begin{verbatim}
   y = eps
\end{verbatim}
which returns \verb|eps| for \verb|double| precision values. For most
typical processors, this value is approximately \verb|2^-52|, or 2.2204e-16.
\subsection{Example}

The following example demonstrates the use of the \verb|eps| function,
and one of its numerical consequences.
\begin{verbatim}
--> eps
ans = 
  <double>  - size: [1 1]
 2.220446049250313e-16  
--> 1.0+eps
ans = 
  <double>  - size: [1 1]
 1.0000000000000002  

\end{verbatim}
