object --+ | SVDSuperimposer
SVDSuperimposer finds the best rotation and translation to put two point sets on top of each other (minimizing the RMSD). This is eg. useful to superimpose crystal structures.
SVD stands for Singular Value Decomposition, which is used to calculate the superposition.

Set the coordinates to be superimposed. coords will be put on top of reference_coords. o reference_coords: an NxDIM array o coords: an NxDIM array DIM is the dimension of the points, N is the number of points to be superimposed. |
