How can I create a newcommand (for latex preamble, using lyx) which its arguments are more than one character?
Specifically, I'm trying to create myself a shortcut for the Rank–nullity theorem and tried to set the following latex preamble I wrote: (I've set
\Ima command to
It works fine if every argument is only one character:
\dimthm VT will produce:
dim V = dim Im T + dim ker T
But if for example my transformation is
LALA I won't be able to get
dim V = dim Im LALA + dim ker LALA
Is it possible?
I've saw a few similar question over here, but couldn't make any solution work.
