ISmDerivative.DiffVariables

Syntax

DiffVariables: String;

Description

The DiffVariables property determines the set of differentiation variables.

Comments

The variables should be separated by a semicolon. Variable name must match the name specified in the function formula.

Suppose, that the following function is specified in the ISmDerivative.Expression property: A1 + A2 * A2 + A3 * A3 * A2. Thus, the following variables can be used as differentiation variables: A1, A2, and A3. As the value of the DiffVariables property you can specify the following: A2;A1.

Example

The property use is given in the example for ISmDerivative.CoefficientsOrder.
