Suppose a square matrix $A$ is dependent upon a set of parameters $\left\{ \lambda _1, \lambda _2, \dots, \lambda _n \right\}$. By changing the $\lambda_i$'s, we can make the eigenvalues of $A$ lie in the left-half of $s$-plane.
Is there some quick method (instead of exhaustive search) to get a feasible $\lambda$?
