HomoCoord Hierarchy for MDTools

Class Hierarchy: HomoCoord -> Coord -> Atom -> Vector

Utilities: dist(a,b) - distances between Coords or groups distsq(a,b) - distance squared between Coords angle(a,b,c,[d],[units]) - angle (a,b,c) or dihedral (a,b,c,d) (dist() and angle() also accept tuples of Coords as single arguments.)

angle (
        a,
        b=angledefault,
        c=angledefault,
        x1=angledefault,
        x2=angledefault,
        )

dist ( a,  b=None )

angleconvert (
        angle,
        old,
        new=angledefault,
        )
