AutoAbacus is a powerful equation solving library that finds solutions to equation sets. Equations are passed to AutoAbacus as text, and the program attempts to find a solution that satisfies all constraints. The equations can be linear or polynomial, and can include arbitrary functions. By profiling the types of equations in the system and their dependencies on each other, AutoAbacus uses appropriate solution methods to solve individual subsets of equations. Applications range from use in a business rules engine to solving engineering equation systems.
Brook for GPUs is a compiler and runtime implementation of the Brook stream programming language for modern graphics hardware. The goals for this project are to demonstrate general purpose programing on GPUs, to provide a useful tool for developers who want to run applications on GPUs, and to research the stream language programming model, streaming applications, and system implementations.
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.
FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.
IDL2Matlab is a program for automatically translating a program from IDL into Matlab and Scilab. IDL and Matlab are two major numerical languages for scientists. Scilab is a free Matlab-like language. Many IDL programs have been developed in large facilities studying astrophysics, geology, medicine, and particle and nuclear physics. On the other hand, Matlab is widely used in smaller laboratories, such as universities and national scientific agencies. This program is designed to extend the portability of such IDL programs.
The Kent Retargettable Occam Compiler is a multi-platform Occam 2.1 compiler that is designed to allow the Occam programming language to be used on non-Transputer platforms. Extensions from a subset of the Occam 3 specification and from pi calculus have been added over time. As a result, the version of the language supported by the compiler is also sometimes referred to as Occam 2.5 or Occam-pi.
Matjito is a pluggable library for the rapid computation of mathematical expressions in C++ programs. Its accepts either an expression string with information about the mapping of symbols to variables and functions or an n-ary tree representing the expression. It features an x86 JIT that allows expressions to be computed very quickly, and is comparable or even better than code generated by optimizing C compilers. It can be used on non-x86 CPUs in a slower interpreting mode.
SIMPLE_1 (SIMulation Program for Logistics Engin'g) is a discrete/continuous network-oriented simulation language with general-purpose programming language features. The Linux version of this software includes a project management system to automate integration of user-developed C/C++ code into SIMPLE_1 network models. A user's C/C++ code is interfaced with the SIMPLE_1 modeling language through information embedded in comments in the user's header file(s). SIMPLE_1 produces executable files with the help of the C++ compiler.
