Vertical alignment of subfigures LATEX

问题

I am working on my thesis and I am struggling with placing 2 images next to each other, so that the second image would be centered vertically along the first one. I was also trying to use subfigure instead of subfloat but neither of them works.

This is how it looks alt text http://img51.imageshack.us/img51/1174/screenshot20100224at712.png

and my code is:

\begin{figure}[H]
\centering  \subfloat[H][sparse($\mathbf{A}$)]{\includegraphics[width=0.28\textwidth]{sparsesmall} \label{sparse}}
    \subfloat[H][full($\mathbf{A}$)]{\includegraphics[width=0.55\textwidth]{fullsmall}\label{full}}
  \caption{Representation of $\mathbf{A}$ in MATLAB}
  \label{schematic}
\end{figure}

Any suggestions to make it look better than now? Thx

If you use subfig package, you can do this easily. The solution is in section 5.4 of the manual:

\newsavebox{\tempbox}
\begin{figure}[H]
\sbox{\tempbox}{\includegraphics[width=0.28\textwidth]{sparsesmall}}
\subfloat[sparse($\mathbf{A}$)]{\usebox{\tempbox}\label{sparse}}%
\qquad
\subfloat[full($\mathbf{A}$)]{\vbox to \ht\tempbox{%
  \vfil
  \includegraphics[width=0.55\textwidth]{fullsmall}
  \vfil}\label{full}}%
  \caption{Representation of $\mathbf{A}$ in MATLAB}\label{schematic}
\end{figure}

I haven't tested it, and there may be typos, but it should work.

You can also use \raisebox{x}{\includegraphics[...]{...}} where x is negative to shift it downwards and positive to shift upwards.

My method is using square minipage which centers its contents:

\begin{figure}
\subfloat[Figure a]{%
\begin{minipage}[c][1\width]{0.5\textwidth}%
\includegraphics[clip,width=1\textwidth]{figurea}%
\end{minipage}}\subfloat[Figure b]{\centering{}%
\begin{minipage}[c][1\width]{0.5\textwidth}%
\begin{center}
\includegraphics[clip,width=0.6\textwidth]{figureb}
\par\end{center}%
\end{minipage}}
\caption{main caption}
\end{figure}

This code was generated by LyX, however, so it's a bit ugly.

Another solution (which works with the subcaption package is

\begin{figure}[p]
        \centering
        \begin{subfigure}{.49\linewidth}
            \centering
            \caption{Large Picture}
            \includegraphics{LARGEPIC}
        \end{subfigure}
        \hfill
        \begin{subfigure}{.49\linewidth}
            \centering
            \caption{SMALL PIC}
            \includegraphics{small picture}
            \begin{minipage}{.1cm}
            \vfill
            \end{minipage}
        \end{subfigure} 
        \caption{Two pictures}
\end{figure}

The \vfill alone does not work, that's why it is put into the minipage
