# Adding vertical space in a multi-line equation while using IEEEeqnarray

how can I add vertical space between lines in an equation while using IEEEeqnarray?

Please add a small example of your use of the ieeeeqnarray environment. Also, are you looking to change the space between successive lines globally or on a one-off basis? –  Mico Sep 18 '11 at 22:14

You can use the optional argument for \\:

\documentclass{IEEEtran}

\begin{document}

\begin{IEEEeqnarray}{c}

\end{document}

a) This doesn't seem to address the particular question of the IEEE environments and b) in such an approach you would be better with \\[2mm] as in Gonzalo Medina's answer. –  Andrew Swann Sep 30 at 13:43
