Similar considerations apply to sets of linear equations with more than one unknown. Most of the below functionality described in the core matlab mathematics documentation has equivalent, often identical, functionality more often that not with the same syntax described in the base. For this reason, using sparse matrices can significantly reduce the amount of memory required for data storage. Since the residual is still large, it is a good indicator that more iterations or a preconditioner matrix are needed. Start with a west0479, a real 479by479 sparse matrix, and define b so that the true solution is a vector of all ones. This examples demonstrates the use of a preconditioner.
