Simulink® is a block diagram environment for multidomain simulation and Model-Based Design. It supports simulation, automatic code generation, and continuous test and verification of embedded systems.

This electronic circuit simulator is highly interactive giving the feeling of playing with real components. It's very helpful for experimentation and visualization. It's a desktop version of the Circuit JS.

A virtual simulation environment for electronic circuits with support of digital and analog devices. It also provides virtual instruments and virtual debugging tools.

FreeMat is an environment for rapid engineering and scientific processing. It is similar to commercial systems such as MATLAB from Mathworks and IDL from Research Systems, but is Open Source.

Designed for scientific computation, this language and editor provides low-cost abstraction and safety checks, focusing on matrix operations with syntax parity to scientific papers. It offers math rendering, real-time dimension checks, and intuitive user experience.

PyDSTool is a sophisticated & integrated simulation and analysis environment for dynamical systems models of physical systems (ODEs, DAEs, maps, and hybrid systems).

Giac/Xcas is a free computer algebra system for Windows, Mac OS X and Linux/Unix (license GPL3, for commercial dual-license contact us).

With Euler Math Toolbox, you experience mathematical computations, numerical as well as symbolic, with ease and beauty.

Axiom is a general purpose Computer Algebra system. It is useful for research and development of mathematical algorithms. It defines a strongly typed, mathematically correct type hierarchy. It has a programming language and a built-in compiler.

ASCEND is a free open-source software program for solving small to very large mathematical models. ASCEND can solve systems of non-linear equations, linear and nonlinear optimisation problems, and dynamic systems expressed in the form of differential/algebraic equations.

Create circuits using the graphical user interface as a quick way of modelling the dynamic system. After you create a circuit you may load this file and simulate the circuit 'dynamically' by changing parameters during the circuit simulation.

OpenAxiom, fork of Axiom , is an open source platform for symbolic, algebraic, and numerical computations. It offers an interactive environment, an expressive programming language, a compiler, a large set of mathematical libraries of interest...
