Create recombining trinomial tree
TrinTree = mktrintree(NumLevels,
NumPos, NumStates, NodeVal)
Number of time levels of the tree.
1-by-NUMLEVELS vector containing the length of the state vectors in each time level.
1-by-NUMLEVELS vector containing the number of state vectors in each time level.
(Optional) Initial value at each node of the tree. Default = NaN.
Create a recombining trinomial tree of four time levels with a vector of two elements in each node and each element initialized to NaN.
TrinTree = mktrintree(4, [2 2 2 2], [1 3 5 7]);
