说明：  快速傅里叶变换，是快速计算序列的离散傅里叶变换（DFT）或其逆变换的方法。傅里叶分析将信号从原始域（通常是时间或空间）转换到频域的表示或者逆过来转换。FFT会通过把DFT矩阵分解为稀疏（大多为零）因子之积来快速计算此类变换。(Fast Fourier transform (FFT) is a fast method to calculate the discrete Fourier transform (DFT) of a sequence or its inverse transform. Fourier analysis transforms a signal from its original domain (usually time or space) to its representation in the frequency domain or vice versa. FFT can calculate these transformations quickly by decomposing DFT matrix into product of sparse (mostly zero) factors.)
