Windows操作系统中FFTW的安装与使用(精)

Windows下FFTW库的使用 FFTW由麻省理工学院计算机科学实验室超级计算技术组开发的一套离散傅立叶变换(DFT)的计算库，开源、高效和标准C语言编写. FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST). We believe that FFTW, which is free software, should become the FFT library of choice for most applications.
