SOAPBelow is the example of using the SetMs operation to edit equation parameters. The following information is sent in the requests (SOAP, JSON): an instance of opened modeling container, operation execution parameters, equation settings for the Exponential smoothing method, and a pattern for getting changed data. After execution the operation returns the model that contains the changed equation.
The C# functions SetMsExpSmoothing_grid and SetMsExpSmoothing_opt change the method of equation calculation. Input parameters:
ms. Opened modeling container instance.
modelKey. Key of the model that contains the equation.
eqKey. Equation key.
After executing the function returns a model that contains the equation.
