Abstract :

In this paper the algebraic Riccati matrix equation is used for eigen-decomposition of per-symmetric matrices. This is achieved by similarity transformation and using the algebraic Riccati matrix equation. The process is the decomposition of matrices into small and specially structured sub-matrices with low dimensions for easy finding of eigenpairs. Example show the efficiency of the proposed method.
