Math & Science ⇒ Trace of a Matrix

[Cham]

Apparently, there isn't a built-in command for the matrix trace operation, while there is one for the determinant (\det). I need to confirm this, and what are you doing to write a trace?

Currently, I'm using \mathrm{Tr}, but I frequently have to add some small space if there are some parenthesis or with a small space \mathrm{Tr}\hspace{1pt}.

Hi Cham,

I would use \DeclareMathOperator{\Tr}{Tr} together with amsmath.
