Defining new commands

  1. \def\Exclamation{Please always enjoy!}
  2. On top of \def:

    \newcommand[number-of-arguments]{\command-name}
    {
       %command-body
    }
  3. \newcommand[1]{\Vector}
    {
       \underline{ \mathbf{#1} }
    }
    ...
    $\Vector{a}$.
  4. \newcommand[1]{\Matrix}
    {
       \underline{\underline{ \mathbf{#1} }}
    }
    ...
    $\Matrix{A}$.
  5. Alternatively:
    \renewcommand{\command-name}
    {
       %command-new-body
    }
  6. \renewcommand[1]{\phi}{       \varphi   }
    \renewcommand[1]{\epsilon}{   \varepsilon   }
    ...
    \phi(\epsilon)

    phi: $\phi$, varphi: $\varphi$, epsilon: $\epsilon$, varepsilon: $\varepsilon$.
  7. \newcommand{\Figure}[3]
    {
      \begin{figure}[H]
      \label{#3}
      \centering #1
      \caption{#2.}
      \end{figure}
    }
    ...
    \Figure
    {\includegraphics{figure.pdf}}
    {Title of figure}
    {fig:figure}

   \IfFileExists{#1}
   {
      #1 contents: \input{#1}
   }{
      non-existent: #1

}

\newcommand{\MyListing}[1]
{
   \begin{itemize}
      \foreach \itm in #1
      {
         \item{\MyInclude{\itm}}
      }
   \end{itemize}
}

      Section.1.tex,
      Section.2.tex,
      Section.3.tex,
   }
