There was an earlier question about aligning different parts of two parallel equations in a multiple line environment, and I'm trying to adapt Werner's answer that used an array for my own use. Probably the problem is that I don't fully understand the code I should put directly after \begin{array}
. Here are my code and the output:
\[
\begin{array}{c*{2}{@{{}\mathrel{<}{}}l}}
1 & |z| & |k|\inv \\[\jot]
|k| & |\phi(z)| & \hphantom{|} 1
\end{array}
\]
Why isn't the |z|
in the top of the array centered? How should I fix that? (I also welcome comments about other aspects of the code, if applicable.)
