    Factorized solution of generalized stable Sylvester equations using many-core GPU accelerators 
    Benner, Peter; Dufrechou, Ernesto; Ezzatti, Pablo; Gallardo, Rodrigo; Quintana-Ortí, Enrique S. (Springer-Verlag, 2021-09)
    [EN] We investigate the factorized solution of generalized stable Sylvester equations such as those arising in model reduction, image restoration, and observer design. Our algorithms, based on the matrix sign function, ...

    Further results on generalized centro-invertible matrices 
    Lebtahi Ep-Kadi-Hahifi, Leila; Romero Martínez, José Oscar; Thome, Néstor (Springer-Verlag, 2018)
    [EN] This paper deals with generalized centro-invertible matrices introduced by the authors in Lebtahi et al. (Appl. Math. Lett. 38, 106¿109, 2014). As a first result, we state the coordinability between the classes of ...

    Numerically stable improved Chebyshev-Halley type schemes for matrix sign function 
    Cordero Barbero, Alicia; Soleymani, Fazlollah; Torregrosa Sánchez, Juan Ramón; Ullah, M. Zaka (Elsevier, 2017)
    [EN] A general family of iterative methods including a free parameter is derived and proved to be convergent for computing matrix sign function under some restrictions on the parameter. Several special cases including ...
