To clarify
In[1]:=Subscript[x, y] = {1, 2, 3}
Out1]={1, 2, 3}
To replace the third element I must use :
In[2]:=Subscript[x, y] = ReplacePart[Subscript[x, y], 10, 3]
Out[2]={1, 2,10}
So that now Subscript[x, y] gives:
In[3]:=Subscript[x, y]
Out[3]={1, 2, 10}
This is unwieldy and I was hoping for a little more condensed notation.
However,
when using subscripts this appears appears to be the simplist notation
available.
