Oct 4, 2011 at 3:35 comment added algori David -- yes, indeed. Sorry I didn't mention that.
Oct 4, 2011 at 3:30 comment added David White Ah, never mind. You just have to use the double dollar signs
Oct 4, 2011 at 3:08 comment added David White Thanks. I had to turn the \\'s into \\\'s, but then it worked. How did you center it?
Oct 4, 2011 at 2:50 comment added algori David -- here you are: begin{matrix} M & \to & A \\ f\downarrow & & \downarrow g\\ M' & \to & A' \end{matrix} The result does not look too nice (the arrows are off and the letters $f,g$ are too large) but it's the best I could do.
Oct 4, 2011 at 2:44 comment added David White I know this has been discussed in meta somewhere, but I can never seem to make the commutative diagrams I want to. Could you just copy your code from above and put it in a comment so I could steal it for my answer?
