I want to use “For” here in order to let mathematica calculate my “body-part” several times. But my “body-part” seem a bit large. And then, lot of errors appear. The strange is when I repeat the calculation by my hand that just as “For” should do (just only delete the For[…]), the programm worked.
How can I solve my problem?
Programm:
Where are the variables inside ClearAll defined in your program? It looks like your problem is that you’re giving For 2 arguments instead of the nominal 4. Take a look at For’s documentation for more information.
Note that For is generally considered bad practice in the Wolfram Language, as there is usually a more elegant way to accomplish a task.
The variables inside ClearAll are used in the 2 NDSolve.
OK, I see. May I ask what you’re trying to accomplish by using For?
I want to calculate the 2 NDSolve many times with different parameters automaticly. The attachment is my programm.
Try this modified version. I replaced the Fors with Tables.
Actually, ignore that. Your problem is that you’re using % to reference the result of the previous computation, but % is the output of the most recent cell, not the last line. Try this attachment.
Thank you very very much, the problem is exactly what you said that happened at %. Now, it works! Thanks again!
