GNU Regression, Econometrics and Time-series Library Features - A wide variety of least-squares-based estimators (including two-stage least squares). - Easy, intuitive interface. - Single commands to launch things like augmented Dickey-Fuller test, Chow test for structural stability, Vector Autoregression. - Reads own format ascii data files, Comma Separated Values files, BOX1 files, own format binary databases (allowing mixed data frequencies and series lengths) and RATS 4 databases. Includes a US macro database and a perl script to create a database off economagic.com. See also the gretl data page. - Output models as LaTeX files, in tabular or equation format (not very flexible yet). - Integrated scripting language: enter commands either via the gui or via scripts. - Command loop structure for Monte Carlo simulations. - GUI controller for fine-tuning Gnuplot graphs. - Link to GNU R for further data analysis.

Ipopt (Interior Point OPTimizer, pronounced eye-pea-Opt) is a software package for large-scale nonlinear optimization. Ipopt is written in C++ and is released as open source code under the Eclipse Public License (EPL). It is available from the COIN-OR initiative. The code has been written by Carl Laird and Andreas Wchter, who is the COIN project leader for Ipopt. The Ipopt distribution can be used to generate a library that can be linked to one's own C++, C, or Fortran code, as well as a solver executable for the AMPL modeling environment. The package includes interfaces to CUTEr optimization testing environment, as well as the MATLAB and R programming environments. IPOPT can be used on Linux/UNIX, Mac OS X and Windows platforms. An excellent reference for this library can be found in: Wachter and L. T. Biegler, On the Implementation of a Primal-Dual Interior Point Filter Line Search Algorithm for Large-Scale Nonlinear Programming, Mathematical Programming 106(1), pp. 25-57, 2006

Kig is an application for interactive geometry. FEATURES - Allows the students to interactively explore mathematical figures and concepts using the computer. - Serves as a WYSIWYG tool for drawing mathematical figures and including them in other documents.

METIS is a software package for partitioning unstructured graphs, partitioning meshes, and computing fill-reducing orderings of sparse matrices. Important note: this is not the original METIS, it has been specially patched by EDF to be used by Code_Aster.

Armadillo is a C++ linear algebra library (matrix maths) aiming towards a good balance between speed and ease of use. The syntax is deliberately similar to Matlab. Integer, floating point and complex numbers are supported, as well as a subset of trigonometric and statistics functions. Various matrix decompositions are provided through optional integration with LAPACK, or one of its high performance drop-in replacements (such as the multi-threaded MKL or ACML libraries). A delayed evaluation approach is employed (at compile-time) to combine several operations into one and reduce (or eliminate) the need for temporaries. This is accomplished through recursive templates and template meta-programming. Useful for conversion of research code into production environments, or if C++ has been decided as the language of choice, due to speed and/or integration capabilities.

This library is a C port of the implementation of Limited-memory Broyden-Fletcher-Goldfarb-Shanno (L-BFGS) method written by Jorge Nocedal. The original FORTRAN source code is available at: http://www.ece.northwestern.edu/~nocedal/lbfgs.html

Developed by Jack Dongarra, Jim Bunch, Cleve Moler and Pete Stewart. 1 Feb 84 Used as part of Matlab, and often used to benchmark machines. Otherwise it is a very good linear algebra package.

MathMod is a mathematical modeling software that visualize and animate implicit and parametric surfaces. MathMod supports: 3D and 4D plotting and animation, OBJ output file format, Texture and pigmentation support, Noise and Turbulence effects support, Large set of scripted examples.

The octave-forge package is the result of The GNU Octave Repositry project, which is intended to be a central location for custom scripts, functions and extensions for GNU Octave. contains the source for all the functions plus build and install scripts. This is stk. ---------------------------------------------------------------------------- The STK is a (not so) Small Toolbox for Kriging. Its primary focus in on the interpolation/regression technique known as kriging, which is very closely related to Splines and Radial Basis Functions, and can be interpreted as a non-parametric Bayesian method using a Gaussian Process (GP) prior. The STK also provides tools for the sequential and non-sequential design of experiments. Even though it is, currently, mostly geared towards the Design and Analysis of Computer Experiments (DACE), the STK can be useful for other applications areas (such as Geostatistics, Machine Learning, Non-parametric Regression, etc.).
