New algorithms to reduce a diagonal plus a symmetric semiseparable matrix to a symmetric tridiagonal one and an algorithm to reduce a diagonal plus an unsymmetric semiseparable matrix to a bidiagonal one are considered. The algorithms are fast and stable, requiring a computational cost of O(N2), where N is the order of the considered matrix.
