As Dennis mentioned, they are both abbreviations for index.
As you may have noticed in the previous thread (where the code in the question was originally written by me as well), I sometimes use one, and sometimes the other.
It is not a hard and fast rule, but in general I will use idx for results of a search, and ind if I'm composing an index vector to be used in a vectorized operation. But these are personal preferences, and I don't even always follow this 'rule' myself.
