eqnarray*

Could the Admin. activate the eqnarray environment ¿?

\begin{eqnarray*}

\end{eqnarray*}

That'd be nice.

Re: eqnarray*


Why did the vector cross the road?
It wanted to be normal.

Re: eqnarray*

If it’s just words, better to use {tabular} than {array}, like this:

{tabular} is like {array}, but it treats the contents as if they are put in \mbox.

Re: eqnarray*

Fair enough.
When each entry of the matrix is just a single word, it doesn't make much difference though. Italics aren't terrible.

Re: eqnarray*

No, I mean

This looks nice, but when using \frac, there's not enough space.

That's why eqnarray environment is perfect for alignment.

Re: eqnarray*

Thank you.

Also, the command \implies does not work. It's the same as \Longrightarrow.
