FFTW++ is a C++ header class for the FFTW Fast Fourier Transform library that automates memory allocation, alignment, planning, wisdom, and communication on both serial and parallel (OpenMP/MPI) architectures. In 2D and 3D, hybrid dealiasing of convolutions substantially reduces memory usage and computation time. Wrappers for C, Python, and Fortran are included.

DataFrame
C++ DataFrame for statistical, Financial, and ML analysis
This is a C++ analytical library designed for data analysis similar to libraries in Python and R. For example, you would compare this to Pandas, R data.frame, or Polars. You can slice the data in many different ways. You can join, merge, and group-by the data. You can run various statistical, summarization, financial, and ML algorithms on the data. You can add your custom algorithms easily. You can multi-column sort, custom pick, and delete the data. DataFrame also includes a large... -

FFTW_Ada
An Ada 2012 binding to the FFTW fast Fourier transform library
FFTW_Ada is an Ada binding to the FFTW (fast Fourier transform) library written at MIT by Matteo Frigo and Steven G. Johnson. FFTW is written in C. FFTW_Ada allows calls to FFTW from an Ada program, thus allowing Ada code to compute fast Fourier and certain other related transforms. FFTW_Ada v2 works with FFTW v3 and requires Ada 2012. -

DarkF
DarkF is an FFT optical simulation code for GW inteferometers
...With the Fourier transform method, it is easy to obtain a propagated beam and we can use this code to simulate a simple or a complex system as a Fabry Perot cavity or Advanced detector, like Advanced Virgo, Advanced LIGO or Kagra. It can include reflection and transmission maps from measurements or real mirrors. -

This is a recursive C++ source code of the Fast Fourier Transform algorithm allowing parallelization. Also a performance test and its results on my computer are provided. The Performance test suggest to use 4 threads for parallelization. With this one can beat the implementation in "Numerical Recipes in C++" for large signals with more than 2^16 / 2^17 / 2^18 samples depending on the hardware and software.

MSU's Sparse Fourier Repository
The Home of DMSFT, AAFFT, GFFT, and MSFFT.
A collection of sparse Fourier transform codes developed by faculty at MSU. Currently codes for four different prototype sparse FFTs are here: 1.) DMSFT, implemented by Ruochuan Zhang. This is a fast, stable, noise robust, and *fully discrete* improvement on the ideas in GFFT below. It is THE BEST sparse FFT around!!! If you're looking for AAFFT, try this out first. 2.) -

Stress intensity factor (SIF) calculation from crack tip displacements
The code implements Muskhelishvili's complex function approach to calculate 2D stress intensity factors (modes I+II) from crack tip displacement fields. Surface displacements can be used with a plane stress elastic model. The code uses power/Fourier series expansion and a conformal mapping of an ellipse onto a circle. -

FFTL
Templated Fast Fourier Transform in C++
Now moved to GitHub: https://github.com/CoreyShay/FFTL Provides some relatively easier to use than normal templated FFT classes written in C++. This is currently still a work in progress, but the FFT portion (complex and real) both output the correct results, and the code executes very quickly, around only 30% or so slower than the much more difficult to compile FFTW on SSE enabled platforms. Though optimized code only runs on SSE (x86) based platforms, it's a very simple matter to port... -

Fast Matrix for Java
General purpose matrix utilities for Java in Parallel Computing
Fast Matrix for Java (fm4j) is a general-purpose matrix utility library for computing with dense matrices. fm4j encapsulated different underlying implementations and select the optimal one in run-time depending on the size of the input matrix. Moreover, fm4j employs Java (Tm) Concurrency to take advantage of the computation power of multi-cor processors. -
