I've gotten into the habit of using subscripted variables, invoking the Notation package and Symbolize. Now, I'd like to be able to write something like

In[1]:= Sum[a<sub>i<sub> ,{i,1,2}]
Out[1]:= a<sub>1<sub> + a<sub>2<sub>

but get

Out[1]:= 2 a<sub>i<sub>

I've tried RemoveSymbolize[myBoxes] to get rid of definitions, but it has no effect. I know that

In[2]:= Sum[Subscript[a,i],{i,1,2}]

works as I'd like and may have to do, but I'm curious if the subscripted variables entered using Ctrl+_ can be made to work.

  • $\begingroup$ When you use Symbolize the the complete variable plus subscript is treated as a single symbol -- which is the purpose of the function. To see this wrap Head around your symbolized variable and then try AtomQ. Then try that again with a "normal" subscripted variable. So the "i" that is subscripted is not available for iterations when you use Symbolize ...by design. To remove symbols evaluate ClearNotations. $\endgroup$ – Mike Honeychurch Dec 10 '13 at 20:52

Evaluating as per the image (using a pasted image because symbolize does not paste well) will help clear things up:

  • $\begingroup$ Thanks, I wasn't able to get back to this before now, but I appreciate your quick and clear response. I have the correct "picture" in my head now for how Symbolize works. Now I need to play around and see why the examples for using markup formats in the Exchange (html, LaTeX, etc.) didn't work for me. $\endgroup$ – tes Jan 6 '14 at 17:23
