Math Assistant and Hypertext Notepad for Engineers and Scientists using Windows. Assists with calculating networks of formulae, dynamic simulations, equation solutions, differential, multiple equations and unknowns, with built-in script language. Useful for engineering and scientific computations, trying out algorithms, plotting results, quantitative brain-storming, and documenting problem solutions. User acquires or creates application files called webs to solve particular problems of interest. Webs included with the distribution include: 1) CA -- Cellular automaton simulation 2) CAVE -- Nano Adventure Game illustrating hypertext interface 3) cocomo -- Computes the time to develop software 4) DIBPrinting -- Tells how to print device dependent bitmaps in Windows 5) filter -- simulates simple FIR and IIR filters 6) hamurabi -- plays the old basic computer game hamurabi 7) HEBB -- Illustrates Hebbian learning using a matrix of weighting factors 8) LOGISTIC -- Illustrates the period doubling approach to chaos, using a simple logistic map 9) logo -- Plots a pretty spiral 10) matrix -- solves four linear equations in four unknowns using lu-decomposition 11) payment -- Computes a monthly payment from principal and interest 12) PERT -- Computes the critical path in a simple construction project 13) PIGGY -- Computes the total amount in piggy bank from the number of each kind of coin 14) Quotes -- Selected quotes from famous iconoclasts and others 15) Rkutta -- Illustrates second order differential equation solution using Runge-Kutta method
