class pele.mindist.MeasurePolicy[source]

interface for possible measurements on a set of coordinates

The MeasurePolicy defines an interface which defines how to perform certain measures which are essential for minpermdist on a set of coordinates. For more motivation of this class see TransformPolicy.


find_permutation(X1, X2) find the best permutation between 2 sets of coordinates
find_rotation(X1, X2) find the best rotation matrix to bring structure 2 on 1
get_com(X) calculate the center of mass
get_dist(X1, X2) calculate the distance between 2 set of coordinates
