Node ascendants
A = nodeasc(T,N)
A = nodeasc(T,N,"deppos")
nodeasc is a tree-management utility.
nodeasc
A = nodeasc(T,N) returns the indices of all ascendants of the node N in the tree T.

example
A = nodeasc(T,N,"deppos") returns the depths and positions of all ascendants of the node N in the tree T.

Create a binary tree of depth 3.
t = ntree(2,3);
Recompose two of the nodes. Plot the tree.
t = nodejoin(t,5); t = nodejoin(t,4); fig = plot(t);
Programmatically, in Node Label, change the selected item from Depth_Position to Index.
Depth_Position
Index
plot(t,"setNodeLabel",fig,"Index")
Obtain the indices of all ascendants of the node at depth-position (2,2).

nodeasc(t,[2 2])
ans = 3×1 5 2 0
Obtain the depths and positions of all ascendants of the same node.
nodeasc(t,[2 2],"deppos")
ans = 3×2 2 2 1 1 0 0
dtree
ntree
wptree
Tree, specified as a dtree, ntree, or wptree object.
Tree node, specified as a nonnegative integer or a 1-by-2 vector. You can specify the node by either its index or depth and position.
In the tree, nodes are numbered from left to right and from top to bottom. The root index is 0.
Data Types: double
double
Ascendants of the node N, returned as a column vector of node indices or a two-column matrix containing the depths and positions of the descendants.
If A is a vector, then A(1) is the index of node N
A(1)
If A is a matrix, the ith row of A contains the depth and position of the ith ascendant. The first row of A is the depth and position of node N.
