How can I write these two syntaxes in alternate from?

Rather than trying to use an "Alternate form of eval function", you should just write your code using much simpler and much more efficient indexing. Is there a particular reason why you cannot use indexing?

You'll have to learn good programming-habits and utilise the vectorized capabilities of matlab. This looks like a case where you might get away with multi-dimensional arrays - but that would require all your signals to have the same length. The safer option is to store all signals in a cell-array - there everything goes. Perhaps something like this:
I_all{i,j,k} = getsiganl(filename1);
I_all_smooth{i,j,k} = smooth(sum(I_all{i,j,k},2));
I would also suggest changing the indices i, j and k to i1, i2 and i3 - this makes me more comfortable when it comes to which order they should go in indexing and also leaves i and j for the imaginary constant.

@Bjorn Gustavsson Thank you. This is really what I wanted

Why not simply
Be mindful though that if i,j,k are scalar coordinates, neither the original eval form nor the above make sense.

@Matt J I think I have checked this in prior but haven't worked. Anyway I got the right answer. Thank you
