Entries from node of recombining trinomial tree
extracts entries of a node of a recombining trinomial tree. The node path is
described by the sequence of branchings taken, starting at the root. The top branch
is number 1, the middle branch is 2, and the bottom branch is 3. Set the branch
sequence to 0 to obtain the entries at the root node.

load deriv.mat; FwdRates = trintreepath(HWTree, [1 2 3])
FwdRates = 4×1 1.0279 1.0528 1.0652 1.0591
This returns the rates at the tree nodes located by starting at 0, taking the up branch at the first node, the middle branch at the second node, and finally the bottom branch at the third node.
You can visualize this with the
BranchList — Number of paths by path length
Number of paths (
NUMPATHS) by path length
PATHLENGTH), specified as a matrix containing the
sequence of branchings.
Values — Retrieved entries of a recombining tree
Retrieved entries of a recombining tree, returned a number of values
