Rcpp integration for the Eigen templated linear algebra library
R and Eigen integration using Rcpp. Eigen is a C++ template library
for linear algebra: matrices, vectors, numerical solvers and related
algorithms. It supports dense and sparse matrices on integer,
floating point and complex numbers, decompositions of such matrices,
and solutions of linear systems. Its performance on many algorithms
is comparable with some of the best implementations based on Lapack
and level-3 BLAS. The RcppEigen package includes the header files
from the Eigen C++ template library (currently version 3.2.2). Thus
users do not need to install Eigen itself in order to use RcppEigen.
Since version 3.1.1, Eigen is licensed under the Mozilla Public
License (version 2); earlier version were licensed under the GNU
LGPL version 3 or later. RcppEigen (the Rcpp bindings/bridge to
Eigen) is licensed under the GNU GPL version 2 or later, as is the
rest of Rcpp.
Semigroupoids: Category sans id
Provides a wide array of semigroupoids and operations for working with
semigroupoids. A Semigroupoid is a Category without the requirement of
identity arrows for every object in the category.
Anything that associates
In mathematics, a semigroup is an algebraic structure consisting of a
set together with an associative binary operation. A semigroup
generalizes a monoid in that there might not exist an identity element.
It also (originally) generalized a group (a monoid with all inverses) to
a type where every element did not have to have an inverse, thus the
name semigroup.
Numerical computing environment
FreeMat is a free environment for rapid engineering and scientific
prototyping and data processing. It is similar to commercial systems
such as MATLAB from Mathworks, and IDL from Research Systems, but is
Open Source.
Vector and affine spaces, linear maps, and derivatives
vector-space provides classes and generic operations for vector spaces
and affine spaces in Haskell. It also defines a type of infinite towers
of generalized derivatives. A generalized derivative is a linear
transformation rather than one of the common concrete representations
(scalars, vectors, matrices, etc).
FFT code and related stuff
fxt is a library package (coming as C++ source code) containing various
algorithms for:
- Fast Fourier Transform (FFT) incl. real-vlued,
- multidimensional and weighted variants.
- Fast Hartley Transform (FHT)
- Number Theoretic Transform (NTT), Fast Walsh Transform.
- Convolution (cyclic, linear and weighted),
- correlation and power spectrum.
- Fast Haar Transform, Fast Wavelet Transform
- Mass storage convolution and fast multiplication routines.
- Sine- and cosine transform (DCT, DST), Fast Z-Transform (FZT)
Library of tools for doing computation in game theory
Gambit is a library of game theory software and tools for the construction
and analysis of finite extensive and normal form games. Gambit is designed
to be portable across platforms.
Gambit includes:
- A graphical user interface, based upon the wxWindows library, providing
a common look-and-feel across platforms.
- The Gambit Command Language, a scripting language with built-in
primitives for constructing and analyzing games.
- A library of C++ source code for representing games, suitable for use
in other applications.
Gnome-based scientific calculator
gdcalc is a financial, statistics, scientific and programmers
calculator for Unix. The GUI was written with glade(1) and uses the
Gnome/Gtk+ toolkit - so it may well be compatible with themes and
other whiz-bang features of those systems.
gdcalc has both Algebraic notation (ie. conventional, TI or Casio
style) and Reverse Polish Notation (RPN or Hewlett-Packard style).
If you've not heard of RPN before, you are probably familiar with
algebraic calculators. Very briefly, while simpler and more natural
to use, RPN calculators need some study eg. they have an Enter key
instead of the equals key.
Visualise multiple 2D-functions of one variable
geg, a GTK+ Equation Grapher is a very simple utility for parsing and plotting
2D-Functions, eg f(x) = 3 + sin(x), and much more complicated functions.
It was written with GTK+ and provides a neat, configurable user interface.
GNU Linear Programming Kit
The GLPK package is a set of routines written in ANSI C and organized
in the form of a callable library. This package is intended for solving
large-scale linear programming (LP), mixed integer linear programming (MIP)
and other related problems.
The GLPK package includes the following main components:
* implementation of the simplex method;
* implementation of the exact simplex method based on
bignum (rational) arithmetic;
* implementation of the primal-dual interior-point method;
* implementation of the branch-and-bound method;
* application program interface (API);
* GNU MathProg modeling language (a subset of AMPL);
* GLPSOL, a stand-alone LP/MIP solver.
