Math & Science ⇒ EqnArray and formula markers in Lyx

[chochmah]

I'm trying to use a formula marker to mark a EqnArray in Lyx. Not a single line in the array but the whole thing. Is there a way to do that? I tried to google the problem but that did not yield any results.

Welcome to the forum!

I suggest to use align instead of eqnarray. That's mainly because eqnarray has a different spacing around relation signs than normal equations. So it's looking bad compared to other math formulas. align does the same much better. Have a look here, there are also sample images of formula output: eqnarray vs. align.

I think the OP is looking for an {aligned} inside an {equation} environment. Then again, I may have misunderstood the ``whole thing'' part ...

Yes, or split within equation. But let's see what he said... for reference: amsmath manual. LyX supports amsmath.

Thank you very much Stefan, I've gotten it to work with align and it looks indeed much nicer. I'll change all my multi line formulas to align.

Cheers!
