本書介紹了科學計算中常用數(shù)值分析的基礎(chǔ)理論及計算機實現(xiàn)方法。主要內(nèi)容包括：誤差分析、插值、函數(shù)逼近、數(shù)值積分和數(shù)值微分、非線性方程的數(shù)值解法、線性方程組的直接解法、線性方程組的迭代解法、常微分方程的數(shù)值解法及相應(yīng)的上機實驗內(nèi)容等。各章都配有大量的習題及上機實驗題目，并附有部分習題的參考答案及數(shù)學專業(yè)軟件Mathematica和Matlab的簡介。
本書采用中、英兩種語言編寫，適合作為數(shù)學、計算機和其他理工類各專業(yè)本科“數(shù)值分析（計算方法）”雙語課程的教材或參考書，也可供從事科學計算的相關(guān)技術(shù)人員參考。
本書采用中、英兩種語言編寫，各章都配有大量的習題及上機實驗題目，并附有部分習題的參考答案及數(shù)學專業(yè)軟件Mathematica和Matlab的簡介。
本書第1 版出版以來，得到了許多專家、同仁及讀者的關(guān)心、支持和幫助，并提出了許多寶貴意見和建議。借再版之機，首先向關(guān)心本書的廣大讀者、專家、同行和本書的各位責任編輯表示由衷的謝意！
在修訂中，為了更適合當前雙語教學的需求，我們保留了原教材的系統(tǒng)和編寫風格（理論部分以中文為主，軟件實現(xiàn)部分以英文為主），注意吸收當前國內(nèi)外教材改革中一些成功的經(jīng)驗，努力體現(xiàn)創(chuàng)新教學理念，以利于激發(fā)學生自主學習，提高實踐應(yīng)用能力，培養(yǎng)綜合素質(zhì)和創(chuàng)新能力。
本次再版修訂的內(nèi)容主要包括以下幾方面：
1．訂正了語言文字表達方面的不足之處，力求用詞規(guī)范，表達確切。
2．剔除了個別內(nèi)容重復和煩瑣之處，使理論部分更好地體現(xiàn)“夠用為度”的編寫原則。
3．恰當?shù)靥幚碛嘘P(guān)定理的證明和有關(guān)例題的求解方法，使其更加通俗易懂。
4．增補了多重積分、有理逼近、Padé逼近等內(nèi)容，進一步體現(xiàn)教材的先進性。
5．結(jié)合增補內(nèi)容，對習題配置作了進一步充實、完善。
6．在實驗部分，大量增加了算法的Matlab 實現(xiàn)程序及相應(yīng)的算例，以便于指導學生實踐應(yīng)用。
本書由浙江臺州學院蘇岐芳副教授主編，浙江臺州學院鄭學良教授、李希文副教授和應(yīng)瑋婷老師參與修訂。具體寫作分工為：第1 章、第2 章及附錄由李希文修訂；第3章由鄭學良修訂；第4章~第8章由蘇岐芳修訂；全書的計算機實驗由應(yīng)瑋婷修訂。
在本書修訂過程中，浙江師范大學徐秀斌教授為本書提出了許多寶貴意見，浙江海洋學院郝彥教授、朱玉輝老師及廈門理工學院陳淑萍老師，對本書的編寫都做了大量工作，在此一并表示衷心感謝！
