IMsDeterministicTransform.Operands

Syntax

Description

The Operands property returns the collection of terms that are used to compile a model equation.

Example

Executing the example requires that the repository contains a modeling container with the KONT_MODEL identifier.

Add links to the Metabase and Ms system assemblies.

After executing the example the model that uses the method of determinate equation is created in the modeling container. The output variable and one input variable are added. The equation of model is built based on the input variable.
