We also present theoretical justifications of the right-preconditioned flexible GMRES for solving consistent linear systems. Numerical experiments on overdetermined and underdetermined linear systems show that the proposed method is superior to the GMRES method preconditioned by NE-SOR inner iterations in terms of total CPU time.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_5_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20736/0002000371","subitem_identifier_reg_type":"JaLC"}]},"item_5_publisher_31":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立情報学研究所","subitem_publisher_language":"ja"}]},"item_5_source_id_32":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-5597","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Du, Yi-shu","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"速水, 謙","creatorNameLang":"ja"},{"creatorName":"Hayami, Ken","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Zheng, Ning","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"保國, 惠一","creatorNameLang":"ja"},{"creatorName":"Morikuni, Keiichi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Yin, Jun-Feng","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-06-09"}],"displaytype":"detail","filename":"20-003E.pdf","filesize":[{"value":"7.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NII Technical Report (NII-2020-003E)：Kaczmarz-type inner-iteration preconditioned flexible GMRES methods for consistent linear systems.","url":"https://repository.nii.ac.jp/record/2000371/files/20-003E.pdf"},"version_id":"8cb66133-5243-4dad-863a-2696ed76a747"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"テクニカルレポート","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Technical Report","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"NII Technical Report (NII-2020-003E)：Kaczmarz-type inner-iteration preconditioned flexible GMRES methods for consistent linear systems.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"NII Technical Report (NII-2020-003E)：Kaczmarz-type inner-iteration preconditioned flexible GMRES methods for consistent linear systems.","subitem_title_language":"en"}]},"item_type_id":"5","owner":"18","path":["136"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-06-09"},"publish_date":"2022-06-09","publish_status":"0","recid":"2000371","relation_version_is_last":true,"title":["NII Technical Report (NII-2020-003E)：Kaczmarz-type inner-iteration preconditioned flexible GMRES methods for consistent linear systems."],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-01-11T06:00:11.715934+00:00"}
