Entries from node of recombining trinomial tree

`Values = trintreepath(TrinTree,
BranchList)`

| Recombining price or interest-rate trinomial tree. |

Number of paths ( |

`Values = trintreepath(TrinTree,
BranchList)` 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.

`Values` is a number of values (`NUMVALS`)-by-`NUMPATHS` matrix
containing the retrieved entries of a recombining tree.

Create a Hull-White tree by loading the example file.

`load deriv.mat; `

Then, for example

FwdRates = trintreepath(HWTree, [1 2 3])

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.

FwdRates = 1.0279 1.0528 1.0652 1.0591

You can visualize this with the `treeviewer` function.

treeviewer(HWTree)
