Say I have a figure with two subfloats inserted using the subfig package. When I reference them with ref{myLabel} I get this

Figure 3.5a and 3.5b.

But what I want is this:

Figure 3.5(a) and 3.5(b).

How can I add the parentheses?

For the subfig package see sections 2.2.2 and 3 of the documentation.

documentclass{article}

usepackage[subrefformat=parens,labelformat=parens]{subfig}



begin{document}

See Figure~subref*{sf1} for more information.

begin{figure}

centering

subfloat[Subfig 1]{label{sf1} Contents of the sub-figure}

qquad

subfloat[Subfig 2]{label{sf2} Contents of the sub-figure}

caption{A figure}

label{fig}

end{figure}

end{document}

(Original answer)

Assuming you're using the subfloat package, section 4 of its documentation indicates you can do something like:

renewcommand*thesubfloatfigure{themainfigure(alph{subfloatfigure})}

to put the sub-number in parentheses.

If anyone came across this question and is using subcaption, here is a solution (borrowed from its excelent manual):

documentclass{article}

usepackage[labelformat=simple]{subcaption}

renewcommandthesubfigure{(alph{subfigure})}



begin{document}

Reference the sub-figure in full form: ref{sf1}.

Referencing just the sub-figure parts: subref{sf1} and subref{sf2}.

begin{figure}

  begin{subfigure}{.48textwidth}

    centering

    Contents of the sub-figure

    caption{Subfig 1}

    label{sf1}

  end{subfigure}

  begin{subfigure}{.48textwidth}

    centering

    Contents of the sub-figure

    caption{Subfig 2}

    label{sf2}

  end{subfigure}

  caption{A figure}

  label{fig}

end{figure}

end{document}

documentclass{article}

usepackage{subfig}



begin{document}

See Figure~ref{fig}subref{sf1} for more information.

begin{figure}

centering

subfloat[Subfig 1]{label{sf1} Contents of the sub-figure}

qquad

subfloat[Subfig 2]{label{sf2} Contents of the sub-figure}

caption{A figure}

label{fig}

end{figure}

end{document}

The [subrefformat=parens,labelformat=parens] options didn't work for me; the references still came out as, e.g., "1b". I had to use

usepackage[caption=false,labelformat=simple]{subfig}

renewcommand{thesubfigure}{(alph{subfigure})}

(I had to use caption=false because without it subfig makes the captions in my document class come out in the wrong style.) Does this seem all right to use? I did discover that under my way, you have to use subref*, not subref, if you want to auto-refer to something like "(a)" (with subref you get "((a))").

Looking at the other answer again, I think I needed to do it this way because I had been using ref for all my references to things like "Figure 1b". (I'd rather not change all my ref's to subref*'s if I can avoid it.)
