- function r = istnode(t,n)
- %ISTNODE Determine indices of terminal nodes.
- % R = ISTNODE(T,N) returns ranks (in left to right
- % terminal nodes ordering) for terminal nodes N
- % belonging to the tree T, and 0's for others.
- %
- % N can be a column vector containing the indices of nodes
- % or a matrix which contains the depths and positions of
- % nodes.
- % In the last case, N(i,1) is the depth of i-th node
- % and N(i,2) is the position of i-th node.
- %
- % The nodes are numbered from left to right and
- % from top to bottom. The root index is 0.
