Dear Group,
This is very simple question.
What is the D function mechanism which let it
to go inside lists. See example
In[1]:=
$Version
Out[1]=
"4.0 for Linux (April 21, 1999)"
In[2]:=
Attributes[D]
Out[2]=
{Protected, ReadProtected}
In[3]:=
D[{x, y, {x}}, x]
Out[3]=
{1, 0, {1}}
Why it goes inside lists if there is no Listable
attribute? The same test is true for 4.1 also.
Sincerely, Arturas
