Fraction-free computation of matrix Padé systems
Bernhard Beckermann, Stan Cabay, George Labahn · 1997
tire present a fraction-free approach to the computation of matrix Pad& systems.The method relies on determining a modified Schur complement for the coefficient matrices of the linear systems of equations that are associated to matrix Pad& approximation problems.By using this modified Schur complement for these matrices we are able to obtain a fast hybrid fraction-free algorithm for their computation.The algorithm is genera] and requires no extra assumptions on its input.
