Using the Runge-Kutta method, SolveDiffEq can solve any number of coupled differential equations of the form
dx(0)/dt = f(0)(t, x(0), x(1), . . . )
dx(1)/dt = f(1)(t, x(0), x(1), . . . )
The Help menu shows how to input a script defining the functions f(0), f(1), . . . so as to numerically solve differential equations of any order or to numerically evaluate any one variable definite integral. Your script is translated into machine language for fast more...
