[Ipopt] Multiple Entries for Triplet matrix format

It is mentioned in the documentation that multiple entries might occur for
the triplet format for matrix representation for some nonzero positions.
What is intended with "the values provided for those positions are added"?

Does it mean the value for that particular nonzero position with multiple
entries should be arithmetically added? Or should it be overwritten with a
later occurring entry?
