void preorder_coord_skip_subtree ( coord_t * subroot )

coord_t* preorder_coord_subtree	(	coord_t *	root,
		coord_t *	last
	)

Note:: Coords, marked with COF_SKIP_TRIVAL (for temporary), and descendants of them will not be trivaled and the flag with be removed after skipping them.

Definition at line 128 of file coord.c.

void update_aggr_matrix ( coord_t * start )

Update aggregate matrices of elements under a sub-tree.

A subtree is specified by the root of it. All elements in the subtree are effected by that changes of matrix of the subtree root.
