Hi~ It's a good map-matching tool and I really appreciate your effort! However, when I implemented this tool, i.e. input the coordinates (.gpx file) and it returns corrected map-matching(.gpx.res.gpx file), the length of them is not the same. The algorithm of literature shows the input and output are one-to-one. I'm wondering whether there is certain params that I left out. THX for your answer!

NOTE: The code I use is the version from @karussell . I just saw it upgraded this week which I'm not try yet.
