Hi, and welcome to LQ,

and can you please rephrase that with a bit more
detail? I have no idea what you're trying to achieve.

Cheers,
Tink

Say, put <-> (leftright arrow) over A. Thanks!

I think that

Code:

\stackrel{\textstyle\leftrightarrow}{A}

should do the trick...

Most welcome :)

I'm pleased to see people using TeX :D

If you are trying to make a vector by placing the arrow above the A, couldn't you just use \vec{A} ? I guess you didn't like the fact that the bottom of the overhead arrow is lost when using vec as opposed to a full arrow?

Oh, I get it now, <->, as in a matrix sort of thing?
