[jira] [Created] (MATH-1449) PolygonsSet.getBarycenter() returns incorrect value for empty region

Matt Juntunen created MATH-1449:
-----------------------------------

             Summary: PolygonsSet.getBarycenter() returns incorrect value for empty region
                 Key: MATH-1449
                 URL: https://issues.apache.org/jira/browse/MATH-1449
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 3.6, 4.0
            Reporter: Matt Juntunen
             Fix For: 4.0


The o.a.c.m.geometry.euclidean.twod.PolygonsSet.getBarycenter() method returns the point (0, 0) when the region is empty. It should return (NaN, NaN) since the barycenter does not exist. This is the behavior of IntervalsSet and PolyhedronsSet.
