The NumericalDerivative type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | BaseStepSize | Sets and gets the base finite difference step size. This assigned value to this parameter is only used if StepType is set to RelativeX. However, if the StepType is Relative, it will contain the base step size computed from Epsilon based on the finite difference order. |
| Center | Sets and gets the location of the center point for the finite difference derivative. |
| Epsilon | Sets and gets the base finite difference step size. This parameter is only used if StepType is set to Relative. By default this is set to machine epsilon, from which BaseStepSize is computed. |
| Evaluations | Number of times a function is evaluated for numerical derivatives. |
| StepSize | Sets and gets the finite difference step size. This value is for each function evaluation if relative step size types are used. If the base step size used in scaling is desired, see Epsilon. |
| StepType | Type of step size for computing finite differences. If set to absolute, dx = h. If set to relative, dx = (1+abs(x))*h^(2/(order+1)). This provides accurate results when h is approximately equal to the square-root of machine accuracy, epsilon. |
