Numerical solution of Sylvester matrix equations in the self-adjoint case
Х. Д. Икрамов, Yu. O. Vorontsov · Moscow University Computational Mathematics and Cybernetics · 2014
Algorithms of the Bartels-Stewart type for numerically solving Sylvester matrix equations of modest size are modified for the case where the linear operators associated with these equations are self-adjoint. The superiority of the modified algorithms over the original ones is illustrated by numerical results.
