Actually, my version returns a vector. It works by 'generalizing' the
input, like this:
1. If the first arg is a string or char matrix, then put it into a
cell array and take note of this.
2. Now the object we have is a cellstr (otherwise an error would be
generated). For every element in the cellstr, check for PATTERN and
put the starting indexes in IDX.
3. If the first arg was a string or char matrix, then take the vector
inside IDX and assign it to IDX.
This way, we can avoid recursion of strfind(). What do you think?

OK :)

I fixed the help message and changed isstr to ischar in my version
(attached). What do you think about it?
