GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content: text, mathematics, graphics, interactive content. TeXmacs can also be used as an interface to many external systems for computer algebra, numerical analysis, and statistics. New presentation styles can be written by the user and new features can be added to the editor using Scheme.
Calcoo is a scientific calculator designed to provide maximum usability. Its features bitmapped button labels and display digits to improve readability, no double-function buttons, undo/redo buttons, copy/paste interaction with the clipboard, both RPN and algebraic modes, two memory registers with displays, displays for Y, Z, and T registers, and tick marks to separate thousands. Calcoo is written in C using the GTK+ widget library (v.2.2+).
RKWard aims to provide an easily extensible, easy to use IDE/GUI for the R project. RKWard strives to combine the power of the R language with the (relative) ease of use of commercial statistical packages. While RKWard is far from finished, it is already useful as an IDE interface to the R language.
Haxial Calculator is a high precision mathematical assistant that evaluates normal (infix) expressions to practically any accuracy. Results can be viewed in normal, fraction, or scientific forms, and it allows you to work in any radix. Worksheets enable you to solve larger problems in a more suitable environment, as well as allowing you to save your work. It also incorporates unit and radix conversion utilities and complete support for variables. Haxial Calculator employs a user interface that allows you to freely type expressions with the keyboard instead of mimicking the button presses of a hand-held calculator.
The Linear and Non-Linear Optimization Solver (or simply the Optimization Solver) is designed to compute an optimized set of decision variables that either maximize or minimize a given objective function while also satisfying a set of arbitrary constraints. It is widely used in the field of operations research, and is a very useful business and scientific tool that will help you make an informed decision on a multitude of complex scenarios that you may encounter in your day-to-day business operations or scientific research.
CONSIDEO MODELER allows you to mindmap a complex problem, analyse it qualitatively to discover levers and bottlenecks, and even to simulate it by automatically building a system dynamics model. One can integrate any external data and setup a customized management cockpit for playing out scenarios. It is useful for organizational problems, project management, financial analysis, production processes, score cards, and much more.
The MATNEM Toolbox is a set of MATLAB objects and classes which provides an interface to the Numerical Econometrics Library, a library of econometric routines written in the C language. The aim of the project is to provide an easy, quick, and object-oriented interface for applied econometric analysis. The NEM library also ensures a good level of performance. Among other features, the MATNEM toolbox contains time series data objects, ultra high-frequency data management algorithms, nonlinear estimation routines (ARMA, multiplicative error models (GARCH, ACD)), and frequentist model averaging algorithms (linear regression model, multiplicative error models (GARCH, ACD)).
