Block power method for computing solvent and spectral factors of matrix polynomials
The authors extend the power method to its block form for use in the block eigenvalue and the associated block eigenvectors of non-symmetric matrices. Algorithms for finding the largest solvent of a monic matrix polynomial are given. These are extended to cover general classes of matrix polynomials. Illustrative examples are also given. Computational complexity and numerical stability are not investigated.
