I think I fixed that this morning, please confirm.

I guess you can manipulate the data any way you like before sending it
in.  This is just the way most algorithms, such as Viterbi, are
defined.

I'd be glad for some suggestions on a different name -- I wasn't quite
sure myself.

It contains the row coordinate for each column.  Using that
information, constructing the values along that path would be easy:

x[path, :] -> values

If there are many equivalent paths, the first is picked.
