| Jun 25, 2017 at 14:28 | comment | added | David Handelman | Let $\Delta$ be the diagonal matrix with entries $r_i$, so that $B = \Delta A$. Then $\exp B = \exp (\Delta A)$. So the answer is almost certainly no, there is no nice way to do it---even in the unlikely case that $\Delta A = A \Delta$. | |
