\section{TEPS Type-based Epsilon Calculation}

\subsection{Usage}

Returns \verb|eps| for double precision arguments and
\verb|feps| for single precision arguments.  The syntax for
\verb|teps| is
\begin{verbatim}
   y = teps(x)
\end{verbatim}
The \verb|teps| function is most useful if you need to
compute epsilon based on the type of the array.
\subsection{Example}

The following example demonstrates the use of the \verb|teps| function,
and one of its numerical consequences.
\begin{verbatim}
--> teps(float(3.4))

ans = 

 1.1921e-07 

--> teps(complex(3.4+i*2))

ans = 

 1.1921e-07 

--> teps(double(3.4))

ans = 

 2.2204e-16 

--> teps(dcomplex(3.4+i*2))

ans = 

 2.2204e-16 


\end{verbatim}
