fixed title.

| Sep 28, 2013 at 17:22 | comment | added | user40607 | That is because A is a correlation matrix. So it has 1s on the diagonal. | |
| Sep 28, 2013 at 17:12 | comment | added | Carlo Beenakker | if A and B are given there is nothing to maximize/minimize; if A is not given, what will stop you from taking A an arbitrarily large multiple of the unit matrix, so that the determinant of A+B will become arbitrarily large? | |
