We are concerned with the solution of an overdetermined system of compatible linear equations whose matrix arises from binomial coefficients with alternating signs, that is the coefficients in the expansion of (1−1)m. Specifically, we address the p

During the last decades, research efforts have been focused on the derivation of effective preconditioned iterative methods. The preconditioned iterative methods are mainly categorized into implicit preconditioned methods and explicit preconditioned

A new class of explicit generalized approximate inverse finite element matrix algorithmic methods, based on the concept of LU-sparse factorization procedures, without inverting the decomposition factors, has recently been introduced. The large sparse
