The main improvements are the following two. The first is that we succeed in developing an algorithm for keeping the orthogonality among eigenvectors in double-precision floating-point number processing without a substantial increase of numerical cost. As a result, all the calculations are done without quadruple-precision floating-point number processing, which is required in [13]. The second is that we implement a deflation effect which substantially decreases numerical cost. As a result of these two improvements, we succeed in developing a program for real symmetric tridiagonal eigenproblem which is even faster than a LAPACK routine DSTEVD, while keeping a numerical accuracy comparable to DSTEVD.","subitem_description_type":"Abstract"}]},"item_119_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"rights: 日本応用数理学会\nrights: 本文データは学協会の許諾に基づきCiNiiから複製したものである\nrelation: IsVersionOf: http://ci.nii.ac.jp/naid/110006197072/","subitem_description_type":"Other"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_other_language_22":{"attribute_name":"その他の言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"日本応用数理学会"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09172246","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"Kuwajima, Yutaka"},{"subitem_text_value":"Shigehara, Takaomi"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1003896"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学理工学研究科"},{"subitem_text_value":"埼玉大学理工学研究科"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"},{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2006-12"}]},"item_119_version_type_28":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"桑島, 豊"},{"creatorName":"クワジマ, ユタカ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"重原, 孝臣"},{"creatorName":"シゲハラ, タカオミ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1003896.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1003896.pdf","url":"https://sucra.repo.nii.ac.jp/record/13748/files/A1003896.pdf"},"version_id":"45fb5101-34ab-4c8a-bb86-5ef5d0d4d8e9"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"実対称三重対角固有値問題に対する多分割の分割統治法の改良(理論, 行列・固有値問題の解法とその応用, <特集>平成18年研究部会連合発表会)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"実対称三重対角固有値問題に対する多分割の分割統治法の改良(理論, 行列・固有値問題の解法とその応用, <特集>平成18年研究部会連合発表会)"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-10-22"},"publish_date":"2009-10-22","publish_status":"0","recid":"13748","relation_version_is_last":true,"title":["実対称三重対角固有値問題に対する多分割の分割統治法の改良(理論, 行列・固有値問題の解法とその応用, <特集>平成18年研究部会連合発表会)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:24:47.142137+00:00"}
