数值分析__(第七版__翻译版)_11467103.pdf
说明: 本書介紹現代的數值近似方法,解釋這些方法如何、為何,以及何時有用,以作為進一步研讀數值分析與科學計算的基礎。修習本書,學生將學會辨別須使用數值方法求解之問題的種類,及使用這些方法時,誤差傳遞的實例;對無法求得確解的問題,應能求得精確的近似解,並學會估計此近似解誤差界限的方法。書中介紹的數值方法,由數學分析、計算法則到實例,皆有系統的說明。本書對於任何要使用數值方法的學系,均可作為良好的基礎教材,同時也是一本內容完備的參考書籍。(This book introduces modern numerical approximations, explaining how, why, and when they are useful as a basis for further study of readings and scientific calculations. In this book, students will learn to identify the types of problems that must be solved using numerical methods, and examples of error propagation when using these methods; for problems that cannot be solved, an accurate approximate solution should be obtained and learn to estimate this. The numerical methods introduced in the method of approximating the error bounds are systematically explained by mathematical analysis, calculation rules and examples. This book can be used as a good basic textbook for any department that wants to use numerical methods. It is also a complete reference book.)

KFFT
计算离散傅里叶变换的一种快速算法,简称FFT。快速傅里叶变换是1965年由J.W.库利和T.W.图基提出的。采用这种算法能使计算机计算离散傅里叶变换所需要的乘法次数大为减少,特别是被变换的抽样点数N越多,FFT算法计算量的节省就越显著。(A computing discrete Fourier transform fast algorithm, referred to as FFT. Fast Fourier Transform in 1965 by the JW Cooley and TW Tuji Ti out. Using this algorithm enables a computer to calculate the number of multiplications needed for the discrete Fourier transform greatly reduced, especially sampling points N is transformed more and save FFT algorithm to calculate the amount of the more remarkable.)
