| Mar 8, 2014 at 22:17 | comment | added | whuber♦ | Even in the case where $Q$ is a scalar you will need a numerical solver because the basic form of the equation is $\log(Q)=aQ+b$ for constants $a$ and $b$. Although conceivably a closed formula could be developed in terms of the Lambert W function it likely would not be of much help. | |
