Parallel Three-Dimensional Fast Fourier Transforms 2.3.1 (Default branch)

Parallel Three-Dimensional Fast Fourier Transforms, dubbed P3DFFT, is a library for computing 3D FFTs using 2D (pencil) decomposition. It is written using Fortran with MPI, and is tuned to work on multiple single-CPU systems (up to 32768 of them). It is built to leverage high-performance serial 1D FFT libraries, such as FFTW or ESSL.License: Public DomainChanges:
An option has been added to overwrite the(complex) input array when using thecomplex-to-real transform with FFTW. An option hasbeen added to use data layout using unit-stride onoutput of the real-to-complex routine, i.e.(Z,X,Y) ordering.

GSL(3)                                                       Library Functions Manual                                                       GSL(3)

NAME

       gsl - GNU Scientific Library

SYNOPSIS

       #include <gsl/...>

DESCRIPTION

       The  GNU  Scientific  Library  (GSL) is a collection of routines for numerical computing.  The routines are written from scratch by the GSL
       team in C, and present a modern Applications Programming Interface (API) for C programmers, allowing wrappers to be written for  very  high
       level languages.

       The library covers the following areas,

              Complex Numbers
              Roots of Polynomials
              Special Functions
              Vectors and Matrices
              Permutations
              Combinations
              Sorting
              BLAS Support
              Linear Algebra
              Eigensystems
              Fast Fourier Transforms
              Quadrature
              Random Numbers
              Quasi-Random Sequences
              Random Distributions
              Statistics
              Histograms
              N-Tuples
              Monte Carlo Integration
              Simulated Annealing
              Differential Equations
              Interpolation
              Numerical Differentiation
              Chebyshev Approximations
              Series Acceleration
              Discrete Hankel Transforms
              Root-Finding
              Minimization
              Least-Squares Fitting
              Physical Constants
              IEEE Floating-Point

       For  more  information please consult the GSL Reference Manual, which is available as an info file.  You can read it online using the shell
       command info gsl-ref (if the library is installed).

       Please report any bugs to bug-gsl@gnu.org.
