The relative efficiencies of these methods are compared to that of Faddeeva's method. An efficient method is then chosen which can be used to compute the coefficients of the characteristic polynomial with a minimum number of multiplications.born digitalarticleseng©1987 IEEE.Copyright and other restrictions may apply.
