I want to use a binary operator (like union or otimes as a large operator (like int or sum). How can I do that?
You have to define the symbol you want to use as a user-defined
symbol first. See Documentation/FAQ/Formula/I_need_a_symbol_that_Math_does_not_provide._What_can_I_do? I need a symbol that Math does not provide. What can I do? for instructions;
most of the symbols used by Math are part of the StarMath
font.
Let's say you have defined the union symbol as the user-defined symbol %union. You can then enter for example
oper%union from i in I A_i
in order to typeset the formula
Note: In build 633 this doesn't work if there is a space before %union (this is a bug in the parser).
Any user-defined symbol can be used as a large operator if it is preceded with oper as in the example.
