Setting Up Parameters of the Determinate Equation Method

Below is the example of using the SetMs operation to edit equation parameters. The request contains an instance of opened modeling container, parameters of operation execution, equation settings for theDeterminate Equation method, and the pattern for getting changed data. After execution the operation returns the model that contains the changed equation.

To execute the example, the equation must include input and output variables.
