Gilles commented on MATH-1284: ------------------------------ I don't know. It's not quite clear that there isn't anything to fix. This is the kind of issues that IMHO calls for separation of concerns (i.e. separate components for separate domains of expertise). > Vector is-not-a Point > --------------------- > > Key: MATH-1284 > URL: https://issues.apache.org/jira/browse/MATH-1284 > Project: Commons Math > Issue Type: Bug > Affects Versions: 3.5 > Reporter: Roman Werpachowski > Priority: Minor > > The class hierarchy for geometry claims that Vector is-a Point: > https://commons.apache.org/proper/commons-math/apidocs/org/apache/commons/math3/geometry/Point.html > This is mathematically incorrect, see e.g. > http://math.stackexchange.com/a/645827 > Just because they share the same numerical representation, Point and Vector > shouldn't be crammed into a common class hierarchy. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
