Additionally, we solve some linear systems with simple coefficient matrices to examine stability of the GMRES method. As a result, we confirm the algorithm is more stable than Symmetric Gauss-Seidel method, and the preconditioning works well. We also find that under very ill-condition cases, the GMRES method shows unstable behavior.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
