## Updated 04 Mar 2006 MATNEM

 Pop 11.83 54.11

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)).

## Updated 29 Sep 2008 GraSy

 Pop 8.83 44.6

GraSy is a tool that converts context-free grammars, which are written in the "Backus-Naur Form" (BNF), into syntax diagrams and the other way around. The grammar and the syntax diagrams can be saved with g2s-file. It is also possible to export syntax diagrams as PostScript files. To keep a good overview while creating syntax diagrams it is possible to change the zoom level.

## Updated 27 Jul 2010 The Frink Language

 Pop 393.91 19.16

Frink is a calculating tool and programming language designed to help you in the real world. It tracks units of measurement throughout all calculations and ensures that answers are correct. It converts between systems of measurement, and has a huge library of physical data. It is both a simple calculator for quick calculations and a full-fledged programming language for large tasks. It draws high-quality graphics, handles conversions between time zones, currencies, and historical values of the U.S. dollar and the British pound, translates between several languages, does date/time math, and more.

## Updated 14 Dec 2003 lambda

 Pop 20.59 2.03

Lambda is an interactive Lambda calculus interpreter. It reduces lambda expressions and converts them into the S, K, and I combinators (ext). It has the ability to associate names with lambda expressions (def), load definitions from a file (load), and list current definitions (list). Lambda expressions representing integers are automatically defined as needed. Many interesting combinators are provided in a definition file. Various settings are provided to influence the way reduction and extraction are performed (set). A short manual is provided showing how lambda works.

## Updated 04 Oct 2004 reken

 Pop 14.28 2

reken is an command-line calculator based on a C coded expression evaluator. It can use user-defined functions and variables. Functions can be integrated (numerically) and differentiated (numerically). An input file can be used for complete calculations or to set up the command-line environment before use (things like PI and some standard functions can be set). Integrating is not fast and not very precise, but should suit hobby calculation needs.

## Updated 19 Aug 2009 Scientific Calculator Midlet

 Pop 61.97 1.9

Scientific Calculator Midlet is a midlet with the following features: scientific operation, different number systems, a traditional user interface, unlimited levels of brackets, 6 memory entries for intermediate results, a preview of the memory contents, an online help system, constants, and user-defined functions.

## Updated 20 Aug 2008 CONSIDEO MODELER

 Pop 81.74 1.7

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.

## Updated 07 May 2002 MuPPEtO

 Pop 12.81 1.01

MuPPEtO stands for Micro (Mu) Primitive Programming Environment. It aims to provide an enhanced editor (written completely in Tcl/Tk) for Octave scripting. It's based on a basic editor which can be extended with plugins.

## Updated 30 Jan 2001 Newmat

 Pop 34.68 1

Newmat, a C++ matrix library, is intended for scientists and engineers who need to manipulate a variety of types of matrices using standard matrix operations. The library includes the operations *, +, -, concatenation, inverse, transpose, conversion between types, submatrix, determinant, Cholesky decomposition, QR triangularisation, singular value decomposition, eigenvalues of a symmetric matrix, sorting, fast Fourier and trig. transforms, printing, and an interface with Numerical Recipes in C.

## Updated 07 Jun 2002 Multi-body Gravity Simulator

 Pop 25.06 1

Multi-body Gravity Simulator (MGS) allows you to perform a simulation based on a fixed time slice. Its unique features are the ability to perform realtime simulations, a three dimensional visualization of the simulation, and the ability to design simulations in XML and with a GUI. The accuracy of realtime simulations will depend on your machine speed. Fixed time step simulations are also supported.
