A NEXT-GENERATION SYSTEM FOR INTERACTIVE SIMULATION

• a proved technique for user-friendly modeling
• powerful and readable mathematical notation
• can serve as a courseware language

SCREEN-EDITED PROGRAMS RUN IMMEDIATELY AT HIGH SPEED

• extra-fast runtime compiler generates efficient code
• no distracting wait for program translation
• keeps your mind on the problem
• truly interactive modeling for design or teaching
• automatically keeps a journal file
• easily add your own help dialogs and menus for teaching

• control-system design, aerospace applications
• chemical and biological processes, physiology
• controls and evaluates multi-run experiments
• optimization and model matching

• fixed and variable-step Runge-Kutta rules (to 20,000 state variables)
• variable-step-and-order stiff-system rules (to 600 state variables)
• difference equations, sampled-data systems
• nonlinear operators, time delays, function memory
• color CRT graphics, hard copy
• easy to add neural networks, fuzzy logic

• editor windows provide familiar editing and file operations
• programs can be run from multiple editor windows to compare models
• simply drag-and-drop user programs, help screens, and notes
• program your own special editing dialogs for interactive simulation
