Ch is an embeddable C/C++ interpreter for cross-platform scripting, shell programming, 2D/3D plotting, numerical computing, and embedded scripting. It is the simplest solution to numerical computing and visualization in the domain of C/C++. It supports the ISO 1990 C Standard (C90), major features in C99 (complex numbers, variable length arrays or VLAs, type generic functions, long long data type, etc), classes in C++, and extensions to the C language like nested functions, string types, etc. It can be embedded in other applications and hardware and used as a scripting language. C/C++ code is interpreted directly with no compilation to intermediate code. It supports Linux, Windows, MacOS X, Solaris, HP-UX, and FreeBSD.
DISLIN is a high-level, easy-to-use plotting library for displaying data as curves, bar graphs, pie charts, 3D-colour plots, surfaces, contours, and maps. Several output formats are supported, such as X11, VGA, PostScript, PDF, CGM, HPGL, TIFF, and PNG. Plotting extensions for the interpreter-based languages Perl, Python, and Java are also supported for most operating systems.
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.
VULCAN (Viscous Upwind aLgorithm for Complex flow ANalysis) offers computational fluid dynamics for subsonic speed through hypersonic turbulent reacting and non-reacting flows on a variety of serial and parallel computational platforms. The computational cost of propulsion flow analysis is reduced through the use of special turbulent wall treatments, multi-grid methods for elliptic and space marching schemes, and conditioning of the governing equations to reduce numerical stiffness. Physical modeling capabilities are improved through the inclusion of models for compressibility, Reynolds stress anisotropies, turbulent diffusivity, finite rate chemistry, and turbulence/chemistry interaction effects. VULCAN can simulate two-dimensional, three-dimensional, or axi-symmetric multi-block problems.
LayoutEditor is an IC/MEMS layout editor. It features all angle elements, a font generator, macros, Boolean operations, drc, netlist-driven layout, LVS, and cross-platform compatibility. Supported formats include Calma GDSII, OASIS (Open Artwork System Interchange Standard), DXF, CIF (Caltech Intermediate Form), Gerber, DEF/LEF, and many others.
Scheture is a hierarchical schematic capture system with built-in netlisters for Spice and Verilog. It has built-in plotting for Postscript, HP PCL and HP GL/2 printers and plotters. It includes a set of symbol primitives, and allows user-defined symbol primitives to allow for extensive customization of primitive properties. The system supports wire buses and iterated instances. The system also supports global pins and implicitly connected pins on a specific sheet. Supported platforms include Solaris and Linux (32- and 64-bit).
Evolvica is an evolutionary computation framework written in Java. The aim of the project is to provide a toolkit that enables developers to create genetic/evolutionary algorithms with minimal programming effort. The toolkit has a modular architecture and is highly extensible. It includes a visual algorithm editor, a source code editor, and a debugger.
Koalog Constraint Solver is a powerful constraint solver written in Java. It provides cutting-edge technology for solving satisfaction and optimization problems, including scheduling, time-tabling, resource-allocation, puzzles (sudoku.koalog.com is powered by Koalog Constraint Solver), and configuration (Koalog Configurator is powered by Koalog Constraint Solver).
SAOimage is a utility for displaying astronomical images under X11. Image files can be read directly, passed through a named pipe under Unix, or from a VMS mailbox from IRAF display tasks. It provides options for zooming, panning, scaling, coloring, pixel readback, display blinking, and region specification.
