For a lot of options the answers are available, but they are not always easy to find. You could try looking at various places in the Mathematica Book, look at the online help, read a collection of tutorials available from Worfram Research (6 years old though). You might also check some books about Mathematica and issues of the Mathematica Journal. Note: When you check online help, be sure to check "Further Examples" for the command you are reading about. ------- |Hi Ted, |you surely know of other commands with, say, Help-non-documented options. |If you know an option of a command, do you know how to find out the |settings available for that option? (Even less what you want.) | |JCrgen | |---------- |> From: Ersek_Ted%PAX1A@mr.nawcad.navy.mil To: mathgroup@smc.vnet.net |> To: mathgroup@smc.vnet.net |> Subject: [mg11774] [mg11745] RE: [mg11624] Re: odd behavior of NDSolv |> Date: Thursday, March 26, 1998 3:09 AM |> |> |> The information below indicates a non-default for the MaxStepSize option |> can be used to fix the problem.
