- Digitizing software for converting graphs and maps into numbers. Image files from scanners, digital cameras and screenshots are easily converted, and exported into spreadsheets. Introduction This open source, digitizing software converts an image file showing a graph or map, into numbers. The image file can come from a scanner, digital camera or screenshot. The numbers can be read on the screen, and written or copied to a spreadsheet. The process starts with an image file containing a graph or map. The final result is digitized data that can be used by other tools such as Microsoft Excel and Gnumeric. Engauge (from en "make" and gauge "to measure") verb meaning to convert an image file containing a graph or map, into numbers. The term "Engauge" in Engauge Digitizer was invented for this project, since there seems to be no similar term in common use. Why Would You Need This Tool? Here are some real-life examples: You are an engineer with some graphs in decades-old documents, but you really need the numbers represented in those graphs so you can do analyses that will determine if a space vehicle is safe to fly. You are a graduate student gathering historical data from charts for your thesis. You are a webmaster with visitor statistics charts and you want to do statistical analyses. You ride a bike or boat and want to know how much distance you covered in your last trip, but you do not have an odometer or GPS unit. However, you do have a map. Nice Features Automatic curve tracing of line plots Automatic point matching of point plots Automatic axes matching Automatic grid line removal for improved curve tracing Handles cartesian, polar, linear and logarithmic graphs Support for drag-and-drop and copy-and-paste makes data transfer fast and easy Image processing tools highlight data by removing grid lines and backgrounds Status bar suggestions guide beginners Context sensitive popup help windows reveal explain feature of the user interface Tutorials with pictures explain strategies for common operations Browser-based user manual is extensive yet easy to navigate Preview windows give immediate feedback while modifying settings Dates and times are imported with the Date/Time Converter Import support for common image file formats such as BMP, GIF, JPEG, PNG and XPM Export support for common software packages such as Microsoft Excel, OpenOffice CALC, gnuplot, gnumeric, MATLAB and Mathematica Engauge is available for a wide variety of platforms (Linux, Mac OSX, Windows) Engauge Digitizer is completely open source and free courtesy of Sourceforge, Trolltech and FFTW
- SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. SymPy is written entirely in Python and does not require any external libraries.
- This library is written in Modelica. The purpose of this library is to calculate fluid properties from an equation of state (EoS), directly within Modelica and not from an external dll. It supports EoS of the form f=f(T,d) meaning Helmholtz energy as a funtion of temperature and density. In addition to all state properties, this library calculates viscosity, thermal conductivity and surface tension. So far, the fluids n-Butane, R134a and Isobutane are implemented, but not fully validated. The next fluids to be implemented are probably isopentane, propane, ammonia, CO2 and other possible working fluids for Organic-Rankine-Cycles.

- This page describes the features of the SVG Rasterizer utility that comes with the Batik distribution. The SVG Rasterizer is a utility that can convert SVG files to a raster format. The tool can convert individual files or sets of files, making it easy to convert entire directories of SVG files. The provided formats are JPEG, PNG and TIFF, however the design allows new formats to be added easily. In addition, the rasterizer can (despite its name) transcode to PDF.
- The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers. It is free software under the GNU General Public License. The library provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting. There are over 1000 functions in total with an extensive test suite. The complete range of subject areas covered by the library includes, Complex Numbers Roots of Polynomials Special Functions Vectors and Matrices Permutations Sorting BLAS Support Linear Algebra Eigensystems Fast Fourier Transforms Quadrature Random Numbers Quasi-Random Sequences Random Distributions Statistics Histograms N-Tuples Monte Carlo Integration Simulated Annealing Differential Equations Interpolation Numerical Differentiation Chebyshev Approximation Series Acceleration Discrete Hankel Transforms Root-Finding Minimization Least-Squares Fitting Physical Constants IEEE Floating-Point Discrete Wavelet Transforms Basis splines Unlike the licenses of proprietary numerical libraries the license of GSL does not restrict scientific cooperation. It allows you to share your programs freely with others.
- MinGW, a contraction of "Minimalist GNU for Windows", is a minimalist development environment for native Microsoft Windows applications. MinGW provides a complete Open Source programming tool set which is suitable for the development of native MS-Windows applications, and which do not depend on any 3rd-party C-Runtime DLLs. (It does depend on a number of DLLs provided by Microsoft themselves, as components of the operating system; most notable among these is MSVCRT.DLL, the Microsoft C runtime library. Additionally, threaded applications must ship with a freely distributable thread support DLL, provided as part of MinGW itself). MinGW compilers provide access to the functionality of the Microsoft C runtime and some language-specific runtimes. MinGW, being Minimalist, does not, and never will, attempt to provide a POSIX runtime environment for POSIX application deployment on MS-Windows. If you want POSIX application deployment on this platform, please consider Cygwin instead. Primarily intended for use by developers working on the native MS-Windows platform, but also available for cross-hosted use, (see note below -- you may need to follow the "read more" link to see it), MinGW includes: A port of the GNU Compiler Collection (GCC), including C, C++, ADA and Fortran compilers; GNU Binutils for Windows (assembler, linker, archive manager) A graphical and a command-line installer for MinGW and MSYS deployment on MS-Windows MSYS, a contraction of "Minimal SYStem", is a Bourne Shell command line interpreter system. Offered as an alternative to Microsoft's cmd.exe, this provides a general purpose command line environment, which is particularly suited to use with MinGW, for porting of many Open Source applications to the MS-Windows platform; a light-weight fork of Cygwin-1.3, it includes a small selection of Unix tools, chosen to facilitate that objective, and using it is a necessary prerequisite for building mingwPORTs. mingwPORTs are user contributed additions to the MinGW software collection. Rather than providing these "add-ons" as precompiled binary packages, they are supplied in the form of interactive Bourne shell scripts, which guide the end user through the process of automatically downloading and patching original source code, then building and installing it. Users who wish to build any application from a mingwPORT must first install both MinGW and MSYS.
- Texmaker is a free, modern and cross-platform LaTeX editor for linux, macosx and windows systems that integrates many tools needed to develop documents with LaTeX, in just one application. Texmaker includes unicode support, spell checking, auto-completion, code folding and a built-in pdf viewer with synctex support and continuous view mode.
- TeXstudio is a fork of the LaTeX IDE TexMaker and gives you an environment where you can easily create and manage LaTeX documents. It provides modern writing support, like interactive spell checking, code folding and syntax highlighting. Also it serves as a starting point from where you can easily run all necessary LaTeX tools. (you can see more features below) You can run it on Windows, Unix/Linux, BSD and MacOSX systems and modify it if you want, since it is licensed under the GPL. Althought TeXstudio has a lot of additional features, it tries to be like an improved version of Texmaker, so it keeps it look&feel as well as its version number.
- Sweave is a tool that allows to embed the R code for complete data analyses in latex documents. The purpose is to create dynamic reports, which can be updated automatically if data or analysis change. Instead of inserting a prefabricated graph or table into the report, the master document contains the R code necessary to obtain it. When run through R, all data analysis output (tables, graphs, etc.) is created on the fly and inserted into a final latex document. The report can be automatically updated if data or analysis change, which allows for truly reproducible research.
- We focus on scientific/engineering software development using RAD abilities of Python language, accompanied with free scientific libraries such as NumPy and SciPy.

- SciPy (pronounced "Sigh Pie") is open-source software for mathematics, science, and engineering. It is also the name of a very popular conference on scientific programming with Python. The SciPy library depends on NumPy, which provides convenient and fast N-dimensional array manipulation. The SciPy library is built to work with NumPy arrays, and provides many user-friendly and efficient numerical routines such as routines for numerical integration and optimization. Together, they run on all popular operating systems, are quick to install, and are free of charge. NumPy and SciPy are easy to use, but powerful enough to be depended upon by some of the world's leading scientists and engineers. If you need to manipulate numbers on a computer and display or publish the results, give SciPy a try!
