Method Detail

apply

public double apply(double x)

Description copied from interface: IOperator

Applies this operator to a single value, returning the result

Specified by:

apply in interface IOperator

Specified by:

apply in class Op

Returns:

applyInverse

public double applyInverse(double y)

Description copied from class: Op

Applies the inverse of this Op. Throws an error if the inverse function does not exist. Returns Double.NaN if no inverse exists for the specific value of y.

Overrides:

applyInverse in class Op

Returns:

minValue

public double minValue()

Overrides:

minValue in class Op

maxValue

public double maxValue()

Overrides:

maxValue in class Op

minDomain

public double minDomain()

Overrides:

minDomain in class Op

maxDomain

public double maxDomain()

Overrides:

derivative

public double derivative(double y)

Description copied from class: Op

Returns the derivative of this Op for a given input value x i.e. f'(x) where f is the operator

Overrides:

derivative in class Op

Returns:

getInverse

public Op getInverse()

Description copied from interface: IOperator

Gets the inverse of this operator. Returns null if no inverse exists.

Specified by:

getInverse in interface IOperator

Overrides:
