Method Details

getValue

public double[][] getValue(double evaluationTime,
 FiniteDifference1DModel model)

Description copied from interface: FiniteDifference1DProduct

Return the value of the product under the given model.

Specified by:

getValue in interface FiniteDifference1DProduct

Parameters:

evaluationTime - The time at which the value (valuation) is requested.

model - The model under which the valuation should be performed.

Returns:

The random variable representing the valuation result.

getValueAtLowerBoundary

public double getValueAtLowerBoundary(FiniteDifference1DModel model,
 double currentTime,
 double stockPrice)

Description copied from interface: FiniteDifference1DBoundary

Return the value of the value process at the lower boundary for a given time and asset value.

Specified by:

getValueAtLowerBoundary in interface FiniteDifference1DBoundary

Parameters:

model - The model which uses the boundary condition (provides model parameters)

currentTime - The time at which the boundary is observed.

stockPrice - The value of the asset specifying the location of the boundary.

Returns:

the value process at the lower boundary

getValueAtUpperBoundary

public double getValueAtUpperBoundary(FiniteDifference1DModel model,
 double currentTime,
 double stockPrice)

Description copied from interface: FiniteDifference1DBoundary

Return the value of the value process at the upper boundary for a given time and asset value.

Specified by:

getValueAtUpperBoundary in interface FiniteDifference1DBoundary

Parameters:

model - TODO

currentTime - The time at which the boundary is observed.

stockPrice - The value of the asset specifying the location of the boundary.

Returns:

the value process at the upper boundary
