Arguments

Spot

Spot price of the underlying asset (e.g. stock).

vols

Sequence of volatilities.

n

Number of paths simulated.

m

Number of time steps in the simulation.

strikes

Sequence of strikes.

r

Interest rate of the numeraire currency (e.g. EUR).

dr

Dividend rate of the underlying asset.

mT

Maturity time (years).

object

Object of the class PriceSurface that is a matrix of prices at different volatilities and strikes.

x

Object of the class PriceSurface that is a matrix of prices at different volatilities and strikes.

color

Color palette (the default pallet requires package fBasics, if you do not want to load this package, you can set color=NULL or other palette).

...

Not used.

Value

The function returns an object of the class PriceSurface that is a matrix of prices at different volatilities and strikes. Class-specific summary function gives the sequences of volatilities and strikes used, as well as maximum, minimum, and average prices. Class-specific plot function constructs a 3-D plot of the price surface.
