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 pedro
