A numerical method and a code for seeking complex eigenvalues are given with the fundamental matrix method.The treatment of singularity,complex eigenvalue and numerical instability are discussed. The method is used to simulate the instability driven by a temperature gradient [ηi].Numerical results agree well with theoretical analyses.
