UNIDFT: A package of optimized discrete fourier transforms

Abstract We present a package of FORTRAN 77 subprograms to compute the discrete Fourier transform of one-dimensional data sets. A large collection of specialized modules, assembled in a top-down scheme, guarantees high flexibility and efficiency. Comparative timings are given. Title of program: UNIDFT Catalogue Id: AAXR_v1_0 Nature of problem We present a package of FORTRAN 77 subprograms to compute the discrete Fourier transform of one-dimensional data sets. A large collection of specialized modules, assembled in a top-down scheme, guarantees high flexibility and efficiency. Comparative timings are given. Versions of this program held in the CPC repository in Mendeley Data AAXR_v1_0; UNIDFT; 10.1016/0010-4655(87)90071-3 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)摘要 本文提供一套FORTRAN 77子程序包，用于计算一维数据集的离散傅里叶变换（Discrete Fourier Transform）。该子程序包采用自顶向下的架构组装了大量专用模块，可保障极高的灵活性与运算效率，文中还给出了对比计时结果。 程序名称：UNIDFT 目录编号：AAXR_v1_0 问题属性 本文提供一套FORTRAN 77子程序包，用于计算一维数据集的离散傅里叶变换。该子程序包采用自顶向下的架构组装了大量专用模块，可保障极高的灵活性与运算效率，文中还给出了对比计时结果。 门捷列夫数据（Mendeley Data）中的CPC程序库收录的本程序版本：AAXR_v1_0；UNIDFT；10.1016/0010-4655(87)90071-3 本程序源自贝尔法斯特女王大学馆藏的CPC程序库（1969-2019）
