Do you know how I can call a reference to an equation using \ref or \eqref and obtain the (name of the equation) instead of the standard counter?

  • What to you mean, "name of the equation"? How is this name defined?

  • I think what Abramo means is to write something like \eqname{eqn:Stokes} to produce something like Stokes equation in the document (instead of \eqref{eqn:Stokes} which produces (1)). Abramo, am I right? Nov 4, 2010 at 16:09

If you use the amsmath package you can do

  \int_{\partial\Omega} \omega = \int_\Omega d\omega

By \eqref{eqn:Stokes} ...

Is that what you want?

    @Matthew: I'd always recommend using \eqref{eqn:Stokes} instead of (\ref{eqn:Stokes}). By the way, there's a closing brace missing ... Nov 4, 2010 at 16:03
  • Yeah, this is what i was searching for, but unfortunately it doesn't seem to work with 'eqnarray'

    Don't use eqnarray, it is horrible. Use amsmath's align and friends instead. Nov 4, 2010 at 17:48
  • @Hendrik: For some reason I never got into the habit of \eqref although I agree it's better. Thanks also for pointing out my missing brace (and to Khaled I guess for fixing it). Nov 4, 2010 at 17:57

    @Hendrik: I like using the fncylab package and then \labelformat{equation}{(#1)} so that I can just write \ref{eqn:Stokes}. Though then it requires more work NOT to get the parentheses.

The \tag{your name here} construct can be used inside \begin{equation} .. \end{equation} and the amsmath \begin..end{align} constructs in order to give equations visible names instead of numbers:

  \tag{Super Fun Equation}
  y = 3x

Labels can then be used to refer to names in references:

  \tag{Super Fun Equation}
  y = 3x
See \eqref{eqn:super} for an awesome equation % See Super Fun Equation for ...

    I seem to be getting (??) instead of the name. Are there any dependencies I should add? Oct 17 at 6:24
