Add value type to Architectural Data section of Simulink data dictionary

Since R2023b



    dataType = addValueType(archDataObj,dataTypeName) adds a Simulink.ValueType specified as dataTypeName to archDataObj, the Architectural Data section of the data dictionary.


    dataType = addValueType(archDataObj,dataTypeName,SimulinkValueType=valueTypeObj) adds a value type based on the specified Simulink.ValueType valueTypeObj to the data dictionary.

    To add a Simulink.ValueType with a specified name to the data dictionary, use the addValueType function. For an example that shows more of the workflow for related functions, see Create Architectural Data Object and Use It to Configure Architectural Data.

    Create or open a data dictionary. This example adds a value type to the data dictionary MyInterfaces.sldd.

    dictName = "MyInterfaces.sldd";
    archDataObj =;

    Add a value type to the Architectural Data section of a data dictionary. You can set the data type, dimensions, and define a description of the created value type.

    myValueType1 = addValueType(archDataObj,"myValueType1");
    myValueType1.DataType = 'int32';
    myValueType1.Dimensions = '[2 3]';
    myValueType1.Description = "I am a Simulink ValueType";

    This example adds a value type that is the same as an existing Simulink.ValueType to the Architectural Data section of a data dictionary, MyInterfaces.sldd.

    Create or open a data dictionary.

    dictName = 'MyInterfaces.sldd';
    archDataObj =;

    Create and define a Simulink.ValueType object.

    simValueType = Simulink.ValueType;
    simValueType.DataType = 'single';
    simValueType.Min = 11;
    simValueType.Max = 17;
    simValueType.Dimensions = [2 4 3];
    simValueType.Description = 'Simulink value type';

    Using the addValueType function you can add a value data type to the Architectural Data section of the data dictionary that is based on the Simulink.ValueType object created in the previous step.

    myNewValueType1 = addValueType(archDataObj, 'MyNewValueType',...
    myNewValueType1 = 
      ValueType with properties:
               Name: 'MyNewValueType'
           DataType: 'single'
            Minimum: '11'
            Maximum: '17'
               Unit: ''
         Complexity: 'real'
         Dimensions: '[2 4 3]'
        Description: 'Simulink value type'
              Owner: [1×1 Simulink.dictionary.ArchitecturalData]

    Input Arguments
