Description: 离散傅里叶变换是20世纪60年代是计算复杂性研究的主要里程碑之一，1965年Cooley和Tukey所研究的计算离散傅里叶变换(Discrete Fourier Test)的快速傅氏变换(FFT)将计算量从О(n2)下降至О(nlogn)，推进了FFT更深层、更广法的研究与应用。
这是一个傅氏变换的MPI程序，用C语言实现。-Discrete Fourier Transform of the 20th century 60 s computational complexity is a major milestone in one study, in 1965 Cooley and Tukey studied the calculation of discrete Fourier transform (Discrete Fourier Test) fast Fourier transform (FFT) calculation increased from О (n2) dropped to О (nlogn), the FFT to promote deeper, broader research and application of law. This is a Fourier transform of the MPI process, with C language. Platform: |

Description: CurveLab is a collection of Matlab and C++ programs to compute fast
discrete curvelet transform in two and three dimensions.
The 2d software includes the implementations of two algorithms: the
transform using wrapping and the one using unequally-spaced fast
fourier transform (USFFT).
The 3d software includes the in-core, out-core and MPI-based parallel
implementation of the 3d algorithm.
To install the package, see curvelab.pdf.
