MATLAB 2015b question: I am trying to set the initial value of a DataStoreMemory block in my Simulink model. I have created a Simulink.Bus object named MY_BUS and a DataStoreMemory block of that type. For the initial value struct, I did this at the command line: MyInitValue = Simulink.Bus.createMATLABStruct('MY_BUS'); MyInitValue.field1 = ; MyInitValue.field2 = ; etc... Since the I don't populate every single field of MyInitValue, I set Configuration_Parameters->Diagnostics->Underspecified_Initialization_Detection to 'Simplified'. However, when I put 'MyInitValue' in the InitialValue field of the DataStoreMemory, an error message is generated: Invalid setting in 'MyModel.MY_BUS_Data_Store_Memory' for parameter 'InitialValue'. Is there something I am missing?

MATLAB 2015b question: I am trying to set the initial value of a DataStoreMemory block in my Simulink model. I have created a Simulink.Bus object named MY_BUS and a DataStoreMemory block of that type.

For the initial value struct, I did this at the command line:

MyInitValue = Simulink.Bus.createMATLABStruct('MY_BUS');
MyInitValue.field1 = <value1>;
MyInitValue.field2 = <value2>;
etc...

Since the I don't populate every single field of MyInitValue, I set Configuration_Parameters->Diagnostics->Underspecified_Initialization_Detection to 'Simplified'.

However, when I put 'MyInitValue' in the InitialValue field of the DataStoreMemory, an error message is generated:

Invalid setting in 'MyModel.MY_BUS_Data_Store_Memory' for parameter 'InitialValue'.

Is there something I am missing?

Hi Kurt,

I tried setting the initial value of a DataStoreMemory block using the Simulink.Bus object of a demo model. To open the demo model, open it using

>> open_system('busdemo')

I then populate the value of Clock and Pulse fields, but leave the sine field unpopulated. After doing the steps you mentioned, I did not get the Invalid setting for parameter Initial Value error. If you share the details of your model and structure values, then it will help in understanding the issue.
