[Solved] Left lbrace without right rbrace for cases

[Yminus]

I would like to have a formula look like this

I tried this

Code: Select all

%delta (x)= left lbrace{ binom{0 ``x <> 0}{infinity `` x=0} }

but this doesn't work. OOo seems not to accept open lbraces without closing counterparts.
How can this be done?

All bracketing requires matching pairs for left and right bracket. With the simple symbols, '[' matches ']', '(' matches ')' and lbrace matches rbrace. Similarly, 'left <any token>' matches 'right <any token>'.

To do what you want, end your suggestion with right none.

Thanks, it worked.
