Needed when we have to use a similar variable for many places, for instance the same size for figures in one table. Not sure if the use of \def is the best approach, but in the following example it is a very easy way.
% define the common widthsize (ws)
\def \ws {0.4\linewidth}
\begin{figure}[h!]
\begin{center}
\begin{tabular}{cc}
iter. 8 & iter. 15
\\
\includegraphics[width=\ws]{optres_iternet8}
&
\includegraphics[width=\ws]{optres_iternet15}
\\
\includegraphics[width=\ws]{optres_iterpara8}
&
\includegraphics[width=\ws]{optres_iterpara15}
\\
iter. 27 & iter. 44
\\
\includegraphics[width=\ws]{optres_iternet27}
&
\includegraphics[width=\ws]{optres_iternet44}
\\
\includegraphics[width=\ws]{optres_iterpara27}
&
\includegraphics[width=\ws]{optres_iterpara44}
\\
iter. 143 (final) &
\multirow{2}{*}{%
\includegraphics[width=0.56\linewidth,trim=10 0 0 0]
{optres_history}}
\\
\includegraphics[width=\ws]{optres_iternet143}

\includegraphics[width=\ws]{optres_iterpara143}
