principal_direction_extent
(tree)¶ - Calculate the extent of a tree, that is the maximum distance between
- the projections on the principal directions of the covariance matrix of the x,y,z points of the nodes of the tree.
- Input:
- tree : a tree object
Returns: the extents for each of the eigenvectors of the cov matrix eigs : eigenvalues of the covariance matrix eigv : respective eigenvectors of the covariance matrix Return type: extents
