For this purpose I have written a simple MS-Excel 5.0 VBA
Programm. The problem with this is, that it's until now
german VBA, cause of some Microsoft-Policy.
Now in Excel 7.0 they have changed back to english and it
will be o.k. if I or some person will have the 2 hours.
The Simulator works with up to 4 differential equations
and uses the Runge-Kutta (RK4) Integration method with
fixed step-size.
The Spreadsheet and the program are free. The only thing I
don't want is, that some person makes money with it.
