Try Max[mat] and Position[mat, Max[mat]].

$\begingroup$ I used
matvariable asMatrixForm, so thePositionfunction did not work, e.g.,Max /@ mat; Position[mat, Max /@ mat]. Thanks @ Szabolcs. $\endgroup$– FreyApr 2, 2015 at 2:34 -

$\begingroup$ Yes, those tips help. I use
Tableform and it works well :) $\endgroup$– FreyApr 2, 2015 at 2:43
