### Re: a strange size happens when using mimetex's array function

Number of replies: 0r}1\\1\end{array}\right]$$$ and you should see $$A\cdot\left[\begin{array}{r}1\\-1\end{array}\right]=\left[\begin{array}{

r}1\\1\end{array}\right]$$ which is what I think you intended. I also took the liberty of changing your $$${cc}$$$'s to $$${r}$$$'s (since there's just one column, you just need one lcr letter), in case you feel that aligns better.
