Stuttgart, den 20. November 1998 Problem ------- Ich versuche mit MMa 3.0 Vektorfelder darzustellen. Als einfachsten Fall waehlte ich das elektrische Feld EFeld einer Punktladung, das sich als Gradient eines skalaren Potentials phi darstellen laesst. Korrekt funktioniert PlotGradientField3D[ phi ] . Nicht korrekt funktioniert PlotVectorField3D[ EField ] . Es wird einfach das Vektor-Feld { Xx, Yy, Zz } dargestellt .. Details im Anhang in Grad3D.nb ! Was mache ich falsch ? Vielen Dank fuer einen kurzen Hinweis !

The data for the notebook starts with the line of stars above. To get the notebook into a Mathematica-compatible application, do one of the following: * Save the data starting with the line of stars above into a file with a name ending in .nb, then open the file inside the application; * Copy the data starting with the line of stars above to the clipboard, then use the Paste menu command inside the application. Data for notebooks contains only printable 7-bit ASCII and can be sent directly in email or through ftp in text mode. Newlines can be CR, LF or CRLF (Unix, Macintosh or MS-DOS style). NOTE: If you modify the data for this notebook not in a Mathematica- compatible application, you must delete the line below containing the word CacheID, otherwise Mathematica-compatible applications may try to use invalid cache data.
