This is how you run an example barrier on DEKCEV.m
For Black-Scholes valuation, put gamma = 1
Up-and-out call barrier with
spot=100
strike = 100
barrier = 120
term = 1 year
dividend yield = 2.9559% continuously compounded
volatility = 15.0% per annum
risk free rate = 4.8790% continuously compounded
to be broken into following vanillas
with tenures = 2/12, 4/12, 6/12, 8/12, 10/12 and 12/12
and strikes = 120, 120, 120, 120, 120, 120.
