Class DigitalBarrierOptionHestonModelBoundary

java.lang.Object

net.finmath.finitedifference.assetderivativevaluation.boundaries.DigitalBarrierOptionHestonModelBoundary

All Implemented Interfaces:

FiniteDifferenceBoundary

public class DigitalBarrierOptionHestonModelBoundary
extends Object
implements FiniteDifferenceBoundary

Boundary conditions for DigitalBarrierOption under the FDMHestonModel.

State variables are assumed to be (S, v), where S is the asset level and v the variance. The second-state-variable boundaries are left free.

Specified by:

getBoundaryConditionsAtLowerBoundary in interface FiniteDifferenceBoundary

Parameters:

product - The product being valued.

time - The running time.

stateVariables - The state variables specifying the boundary location.

Returns:

The lower-boundary conditions by dimension.

getBoundaryConditionsAtUpperBoundary

public BoundaryCondition[] getBoundaryConditionsAtUpperBoundary(FiniteDifferenceEquityProduct product,
 double time,
 double... stateVariables)

Description copied from interface: FiniteDifferenceBoundary

Returns the boundary conditions at the upper boundary.

The returned array is indexed by state-variable dimension.

Specified by:

getBoundaryConditionsAtUpperBoundary in interface FiniteDifferenceBoundary

Parameters:

product - The product being valued.

time - The running time.

stateVariables - The state variables specifying the boundary location.

Returns:

The upper-boundary conditions by dimension.
