Solution of vectorized equation

56 Views Asked by At

I am looking for a solution (or approximate solution) for the following equations with vectorization. Let $X$ be $m\times n$ matrix of unknown parameters, $A,B$ and $C$ are comfortable matrices (i.e., $A$ be $m\times m$, $B$ be $n\times n$, $C$ be $m\times n$), $vec$ is the vectorization, what's the typical solution of \begin{equation} \ vec\left( AX+XB\right) =vec\left( C\right) \ \end{equation} looks like? Is there anyway to get a solution of $X$ in a simple formula? I am looking for a solution of $vec(X)=?$ Many thanks!
