Ok, I know I should've first read the whole AMSmath documentation before asking this but... this is faster...Say I have a bunch of equations within a labeled subequations environment. Something like (in LaTeX): ... \begin{subequations} \label{eq:eq1} \begin{equation} <Some math> \end{equation} <Some text> \begin{align} <Some math> \\ <Some math> \\ <Some math> \end{align} \end{subequations} ... \ref{eq:eq1} ... The equations are all labeled with the same number and with the roman subnumbers from a through d. As long as I'm aware, I can only \ref{} the main label. I can not make an automatic reference to a particular subequation unless I label it as well. If I don't do it, I have to write the roman subnumber manually. However, if I later on insert another equation within the subequations, I'll have to scan the whole document and fix the subnumbers in all cross references... Does anyone know of a way to automatize this process? Without having to label individual eqs, I mean. Perhaps there's a package in CTAN that I don't know of. And does LyX support it?
Why wouldn't you label the subequation that you specifically want to reference? That's exactly how you should do it, I think. That's how LaTeX handles this problem. Especially if you are worried about perhaps inserting or removing subequations before the referenced one.
