数据挖掘讲义第六章聚类分析,PDF文件大小约520K(Data mining handout Chapter 6 clustering analysis, PDF file size is about 520K)

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.)

重力频率域位场延拓。将观测面的位场数据（a20_mag.gtd）向上延拓3.3m，之后与已知的理论值（a53_mag.grd）进行比较，计算其均方误差；反之，将观测面的位场数据（a53_mag.grd）向下延拓3.3m，之后与已知的理论值（a20_mag.grd）进行比较，计算其均方误差。(gravity frequency field extend)

说明：  利用matlab软件进行数值编程，优化计算。(Matlab software is used for numerical programming and optimization calculation.)
