| Mar 14, 2015 at 19:46 | comment | added | user13113 | It may be simpler to write $sI = (sI-Q) + Q$ and use the alternative form $$ f(s) = w^T v + (w^T Q) (sI-Q)^{-1} v $$ | |
| Mar 11, 2015 at 23:28 | comment | added | user13113 | I'm not sure if it helps, but if we consider diagonal $Q$ (e.g. if we diagonalize), then $\lim_{s \to 0} s(sI-Q)^{-1}$ sends the zero diagonal entries to $1$ and the nonzero diagonal entries to $0$. | |
