“…Such type of splitting leads to the iterative scheme x k+1 = P −1 Rx k − P −1 Sx k−1 + P −1 b, k > 0 for solving the non-singular linear system (1.1), when n = m. Shen and Huang [36] and Miao et al [26] studied the convergence and comparison of the above iterative scheme for monotone matrices (A ∈ R n×n is monotone [13] if and only if A −1 exists and A −1 ≥ 0). Moreover, several convergence and its comparison results exist in the literature for different types of double splittings (see [19], [20], [21], [25], [36], [37], [39], [41], [45]). In 2019, Li et al [23] proposed an alternating scheme using double splittings of a matrix to find an approximate solution of a real non-singular linear system of equations.…”
