Personally I think the default size of square brackets in latex math mode is too small. For example, for an interval [a,b]
, I would prefer \big[\big]
as opposed to plain []
. My question is, what can I do to change the default size of []
, so that when I input []
in math mode, they will show up automatically the same size as \big[\big]
?
Right now I'm defining a new command called \b{}
which takes one argument and inserts it between \big[
and \big]
, but the code looks ugly. Apparently \newcommand
(or \def
or \let
) does not allow [
to be refined.
Any help is much appreciated. Thanks.
