What is the standard notation for the diagonal of a matrix? I believe it is $\displaystyle \Delta$, as with the cartesian product, but I am not sure.

If so, is there another notation for it? As I'm using $\displaystyle \Delta$ for something else...

Standard Notation?

I believe delta is used when your looking for the determinant of a matrix. - Feb 16th 2010, 12:18 AMSwlabr
