\begin{description}

  \FNSPEC{min}{(\kw{real}, \kw{real})}{\kw{real}}
    returns the maximum of its two arguments.
  \FNSPEC{modulate}{}{}
  \FNSPEC{pow}{(\kw{real}, \kw{real})}{\kw{real}}

\section{Kernels}
Diderot knows about a number of standard convolution kernels, which are described in the
following table:
\begin{center}
  \begin{tabular}{r@{ \texttt{:} }lp{3.5in}}
    \multicolumn{2}{c}{\textbf{Specification}} & \textbf{Description} \\ \hline
    \texttt{bspln3} & \kw{kernel\#}\texttt{2} & cubic bspline reconstruction (does not interpolate) \\
    \texttt{bspln5} & \kw{kernel\#}\texttt{4} & quintic bspline reconstruction (does not interpolate) \\
    \texttt{ctmr} & \kw{kernel\#}\texttt{2} & Catmull-Rom interpolation \\
    \texttt{tent} & \kw{kernel\#}\texttt{0} & linear interpolation \\ \hline
  \end{tabular}%
\end{center}%
