Thanks, Joel, your advice is wise. Some subproblems have got an analytical solution, so I can test the accuracy of my simulation, but the final solution isn't obtainable (at least for me) analytically. The speed problem is present, because a million number crunching in the presence of nonlinearities is really a hard job.
For now I decided to use the fastest generator, after some debugging I may use a better method. Ladislav -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with "unsubscribe" in the subject, without the quotes.
