Hi,
I just saw in the OOo-Math guide, that there is a formatting option missing,
that I think, should be added.
Suppose, you need to write a formula that looks like this:
x> 0 1
h = {
x<= 0 0
constructs like this (with a scalable bracket) are very common. You can achieve
something similar with this code:
%tau = left lbrace matrix {x> 0 # 1 ## x<= 0 # 0 } right none
(my example is entirely made up, it means nothing special!)
So left none ore right none determine the "invisible" end of the bracket and tell the
engine to not show anything, not even the usual error "?".

Hi, Sigrid,
Thanks for the heads-up. "none" looks very worthy of inclusion; I'll do
that, probably for 3.4, maybe sooner on the wiki.
I'd love to know where you found out about it. I don't actually use the
Math Engine at all; any help greatly appreciated.
