General ⇒ Renaming \newcommand args from #1 to a variable name

[eggmanneo]

I was wondering if there was a way to replace the name of arguments in \newcommand from #1 to another variable name. For exmple, I have this latex code to write the multivariate normal CDF

Code: Select all

Code, edit and compile here:

1
2
3
\newcommand{\mvncdf}[3]{
\Phi_{#1}\left(#2\middle|#3\right)
}

Run LaTeX here

I would like to replace the #1, #2, and #3 names of the arguments to somethis else, like naming #1 "n" and #3 "\Sigma". Is there a way to do this?

I'm afraid I don't quite understand what you mean... can you add an example code that shows how you would like to use newcommand?

I think I understand what you're after: using named variables in the macro definition like

Code: Select all

1
\newcommand{foo}[bar]{#bar}

But as far as I know that's not possible, and I'm not sure why you should want it. Unless you're after optional arguments with key/value pairs, like in this post on tex.sx.

If that is the goal: this is indeed impossible.
