Constructor Detail

UnaryNumerical

                      EvalEngine engine)

Method Detail

apply

public IExpr apply(IExpr firstArg)

Description copied from interface: Function

Returns the result of applying this function to input. This method is generally expected, but not absolutely required, to have the following properties:

• Its execution does not cause any observable side effects.
• The computation is consistent with equals; that is, Objects.equal(a, b) implies that Objects.equal(function.apply(a), function.apply(b)).

Specified by:

apply in interface Function<IExpr,IExpr>

value

public double value(double x)

Description copied from interface: UnivariateFunction

Compute the value of the function.

Specified by:

value in interface UnivariateFunction

Parameters:

x - Point at which the function value should be computed.

Returns:

the value of the function.

derivative

public UnivariateFunction derivative()

First derivative of unary function

Specified by:

derivative in interface DifferentiableUnivariateFunction

Returns:

the derivative function

value
