How can i get the Initial Value of an Output signal in a StateFlow ?

I want to read the initial value of an output signal in a Stateflow and store it in a variable. I am able to access the object of Data of a Stateflow in the following manner:

SF: is the path of the Stateflow

tmp_SFObj = get_param(SF,'Object')

tmp_ChartObj = tmp_SFObj{1}.find('-isa','Stateflow.Chart')

tmp_SFData = tmp_ChartObj.find('-isa','Stateflow.Data')

But problem arising is that the object 'tmp_SFData' does not have 'Initial Value' as its dataobject variable. How can i get Initial Value of the Output in a variable ??

I am getting following object parameters for an Output signal (No option for Initial Value):

K>> tmp_SFData(1)

ans =

                Path: 'xyz'
                  Id: 690
             Machine: [1x1 Stateflow.Machine]
          SSIdNumber: 117
                Name: 'abc'
         Description: ''
     SaveToWorkspace: 0
           TestPoint: 0
         OutputState: []
            DataType: 'uint8'
               Props: [1x1 Stateflow.DataProps]
          ParsedInfo: [1x1 Stateflow.DataParsedInfo]
        CompiledSize: ''
        CompiledType: 'unknown'
               Debug: [1x1 Stateflow.DataDebug]
                 Tag: []
            Document: ''
               Scope: 'Output'
                Port: 1
    InitializeMethod: 'Expression'
        UpdateMethod: 'Discrete'
         MessageMode: 'NotMessage'
         LoggingInfo: [1x1 Stateflow.SigLoggingInfo]

Thanks for the views guys... I have got the solution. Syntax:

tmp_SF_Value = tmp_SFData.Props.InitialValue;
