Latex

Can anyone help me in writing a matrix in latex?  Looking up sources, I can find ways to do it, but they don't seem to work on this forum.  For example, just display the matrix:

a b c
d e f
g h i

Re: Latex

It seems to me that you can't do matrices with whatever we're runnig here.. At all.. Some documentation/readme would be useful though..

Re: Latex

I managed to do this:

using:

But I I think the forum software is changing the latex code *before* formatting it, and this is  what is making it hard to format the latex properly.

Give me time and I will look into it.

Re: Latex

George, try yours out.  I believe you will find it doesn't work to have latex on multiple lines.

See the problem there?  You want everything in a matrix to get lined up.

Re: Latex

It is a little tricky. You see, the first and most important thing is to "sanitize" the text in the message: to remove or alter characters that could be part of a program (which someone bad may want to run on the forum). And this necessary first step alters *some* LaTeX code (like the &).

So I need to figure a way of preserving the LaTeX code while maintaining the security of the forum.

But I will persist

For George:
Try to write this in LaTeX:
0<1.
