    abstract     = "We describe calculation of eigenvalues of 2x2 and 3x3 Hermitian matrices as used in the analysis of multilook polarimetric {SAR} data. The eigenvalues are calculated as the roots of quadratic or cubic equations. The methods are well suited for fast matrix oriented computer implementation and the speed-up over calculations based on for-loops and built-in eigenproblem solvers is enormous."
