WebMany examples are given in order to compare the use of IR with large values for T and/or u and the use of DS (where both T and u must be small) in the solution of systems whose matrices are large and sparse. The main conclusion is that iterative refinement may effectively be used as an option in many packages for the solution of sparse linear ... WebSparse systems encountered in practical problems are characterized by a very large value of n (several hundreds) and the number of non-zero elements in matrix A is small, …
