    Balanced incomplete factorization preconditioner with pivoting 
    Marín Mateos-Aparicio, José; Mas Marí, José (Springer-Verlag, 2023-01)
    [EN] In this work we study pivoting strategies for the preconditioner presented in Bru (SIAM J Sci Comput 30(5):2302-2318, 2008) which computes the LU factorization of a matrix A. This preconditioner is based on the Inverse ...

    Block pivoting implementation of a symmetric Toeplitz solver 
    Alonso-Jordá, Pedro; Dolz Zaragozá, Manuel Francisco; Vidal Maciá, Antonio Manuel (Elsevier, 2014-05-01)
    Toeplitz matrices are characterized by a special structure that can be exploited in order to obtain fast linear system solvers. These solvers are difficult to parallelize due to their low computational cost and their closely ...
