map

public double map(double value)

Description copied from class: Function

Map a value through the function.

Overrides:

map in class Function

mapDerivative

public double mapDerivative(double value)

Description copied from class: Function

Map a value through the first derivative of this function.

Overrides:

mapDerivative in class Function

mapSecondDerivative

public double mapSecondDerivative(double value)

Description copied from class: Function

Map a value through the second derivative of this function.

Overrides:

mapSecondDerivative in class Function

getMinValue

public double getMinValue()

Description copied from class: Function

Return the smallest possible function value. If no exact value can be produced easily, this should return an estimation (lower bound).

Specified by:

getMinValue in class Function

Returns:

the minimum function result.

getMaxValue

public double getMaxValue()

Description copied from class: Function

Return the largest possible function value. If no exact value can be produced easily, this should return an estimation (upper bound).

Specified by:

getMaxValue in class Function

Returns:

the maximum function result.
