Hello all out there
I use Mathematica 4.2 under FreeBSD (Linux API) and 4.1 (Linux).
I want to demonstrate my students something about grad, div and curl.
So I prepared a notebook on the FreeBSD-machine (Mathematica 4.2),
which worked there OK. Now I want to re-evaluate the notebook at the
university (Mathematica 4.1 on Linux) and I get the following:
-----8<----------8<----------8<----------8<----------8<----------8<-----
In[1]:= << CalculusVectorAnalysis
Cartesian::"shdw": Symbol "Cartesian" appears in multiple contexts \
CalculusVectorAnalysis, Global definitions in context \
CalculusVectorAnalysis may shadow or be shadowed by other \
definitions.
In[2]:= <<GraphicsPlotField3D
<<GraphicsPlotField
<<GraphicsContourPlot3D
<<GraphicsLegend
In[3]:= SetCoordinates[Cartesian[x, y, z]]
Coordinates::"invalid": Cartesian[x, y, z] is not a valid \
coordinate system specification.
Out[3]:= SetCoordinates[Cartesian[x, y, z]]
-----8<----------8<----------8<----------8<----------8<----------8<-----
At this point I can stop evaluating the notebook. :-(
But what is the problem here? Is there a significant difference
between 4.1 and 4.2? A Bug?
Does a workaround exist? (I don't want to update/downgrade to have
both machines at a consistent level)
I couldn't find anything with google (but maybe I didn't look at the
right places -> pointer to them might be enough).
Thanx for any help,
