Convert a number to a vector

I'm working on a code that coverts ASHRAE refrigerant numbers to a chemical formula. I'm trying to convert a number ex: 123 to a vector [1 2 3] (from there the code falls into place). I've looked at this board with a similar question and copying and pasting the codes doesn't look the same for me. The comenters posted this code num2str(1234)*1+'0' => [1, 2 ,3, 4] but when I post the same code with a cleared command window I get the following;

num2str(1234)*1+'0'

ans =

    97    98    99   100

You need to make it clear whether you are dealing with strings of characters or numerical values.

It's supposed to be numerical values.

The commenters were wrong, or you transcribed it with an error. The plus should be a minus:

out = num2str(1234) - '0'

Thank you very much, this fixed it right up.
