GKmap is a free K-Map disclosure software, which is developed to solve
the Digital Electronics design problems. Along with design it also helps
in analysis of information flow in the digital circuits.
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.
OpenGL Mathematics (GLM) is a header only C++ mathematics library for
graphics software based on the OpenGL Shading Language (GLSL) specification.
GLM provides classes and functions designed and implemented with the same
naming conventions and functionalities than GLSL so that when a programmer
knows GLSL, he knows GLM as well which makes it really easy to use.
This project isn't limited to GLSL features. An extension system, based on
the GLSL extension conventions, provides extended capabilities: matrix
transformations, quaternions, half-based types, random numbers, procedural
noise functions, etc...
This library works perfectly with OpenGL but it also ensures interoperability
with third party libraries and SDKs. It is a good candidate for software
rendering (Raytracing / Rasterisation), image processing, physic simulations
and any context that requires a simple and convenient mathematics library.
GraphThing is a tool that allows you to create, manipulate and study graphs.
These "graphs" are mathematical objects that describe relationships between
sets; they are not 2D plots, charts, or anything similar to that.
GotoBLAS2 is a fast implementation of Basic Linear Algebra
Subprograms. It supports various architectures and is optimized
for many cores, including Intel Nehalem and Atom, Via Nano,
SiCortex, AMD Shanghai and Istanbul.
levmar is a GPL-licensed library written in C, that implements the
Levenberg-Marquardt (LM) optimization algorithm, one of the most
effective methods for solving nonlinear least squares problems.
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:

Point Filter Line Search Algorithm for Large-Scale Nonlinear Programming,
