I have the following sequence of commands:
In[108]:=
s=IdentityMatrix[2]
Out[108]=
{{1,0},{0,1}}
In[110]:=
ss[1]=s
Out[110]=
{{1,0},{0,1}}
In[111]:=
ss[1][[1,1]]
Out[111]=
1
In[112]:=
ss[1][[1,1]]=3
Set::setps: ss[1] in assignment of part is not a symbol."
Out[112]=
3
Why can I read the entry ss[1][[1,1]] but can not change its value ?
What do I have to do to change this value ?
Thank's (once more) for any help
