eqptimespec

Specify time structure for Equal Probabilities binomial tree

Syntax

TimeSpec = eqptimespec(ValuationDate,Maturity,NumPeriods)

Description

example

TimeSpec = eqptimespec(ValuationDate,Maturity,NumPeriods) sets the number of levels and node times for an equal probabilities tree (eqptree).

Examples

This example shows how to set the number of levels and node times for an EQP tree by specifying a four-period tree with time steps of 1 year.

ValuationDate = '1-July-2002';
Maturity = '1-July-2006';
TimeSpec = eqptimespec(ValuationDate, Maturity, 4)
TimeSpec = struct with fields:
           FinObj: 'BinTimeSpec'
    ValuationDate: 731398
         Maturity: 732859
       NumPeriods: 4
            Basis: 0
     EndMonthRule: 1
             tObs: [0 1 2 3 4]
             dObs: [731398 731763 732128 732493 732859]

Input Arguments
