Eigen values

[ateestructural]

I know that one gets complex Eigen values when there is damping in the system. IS it possible that if the system is unstable, one gets complex values?

I shall be grateful if someone can provide some insight if come across such a scenario of getting complex Eigen values in an undamped system
