Parallel Three-Dimensional Fast Fourier Transforms 2.3 (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:
A C interface has been added. More examples havebeen added: in-place transform and power spectrumcalculation. Performance improvements have beenmade. Ghost cell support was added fornearest-neighbor communication. Several bugs havebeen fixed.

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.
