Data Properties
Stateflow API objects of type Data have the properties listed in the table below. See also Data Methods.

Property
 Type
 Acc
 Description
DataType
 Enum
 RW
 Data type of this data. Can be 'double' (default), 'single', 'int32', 'int16', 'int8', 'uint32', 'uint16', 'uint8', 'boolean', 'fixpt', or 'ml'.
Equivalent to an entry in the Type column for this data in Explorer or the Type field in the properties dialog for this data.
Debug.
Watch
 Boolean
 RW
 If set to true (default = false), causes the debugger to halt execution if this data is modified. Setting this property to true is equivalent to selecting the Watch column entry for this data in the Explorer or selecting the Watch in debug check box in the properties dialog for this data.
Description
 String
 RW
 Description of this data (default = ''). Equivalent to entering a description in the Description field of the properties dialog for this data.
Document
 String
 RW
 Document link to this data (default = ''). Equivalent to entering the Document Link field of the properties dialog for this data.
Id
 Integer
 RO
 Unique identifier assigned to this data to distinguish it from other objects loaded in memory.
FixptType.Bias
 Double
 RW
 The Bias value for this fixed-point type (default = 0).
FixptType.
FractionalSlope
 Double
 RW
 The Fractional Slope value for this fixed-point type (default = 1).
FixptType.
RadixPoint
 Integer
 RW
 The power of 2 specifying the radix-point location for this fixed-point type (default = 0).
FixptType.
BaseType
 Enum
 RW
 The size and sign of the base integer type for the quantized integer, Q, representing this fixed-point type. Can be 'int32', 'int16', 'int8', 'uint32', 'uint16', or 'uint8' (default).
InitFromWorkspace
 Boolean
 RW
 If set to true (default = false), this data is initialized from the MATLAB workspace. Setting this property to true is equivalent to selecting the FrWS column entry for this data in the Explorer or setting the Initialize from field to workspace in the properties dialog for this data.
Machine
 Machine
 RO
 Machine that contains this data.
Name
 String
 RW
 Name of this data (default = 'datan', where n is a counter of data with the name root data). Equivalent to entering the name of this data in the Name field of its properties dialog. Also can be named (renamed) in the Explorer by double-clicking the entry in the Name column for this data and editing.
OutputState
 State
 RO
 State whose activity this data represents as an output. Create the data for this state through the State method outputData. Equivalent to selecting Output State Activity property for this state.
ParsedInfo.
Array.
Size
 Integer
 RO
 Numeric equivalent of Data property Props.Array.Size, a String (default = []).
ParsedInfo.
Array.
FirstIndex
 Integer
 RO
 Numeric equivalent of Data property Props.Range.FirstIndex, a String (default = 0).
ParsedInfo.
InitialValue
 Double
 RO
 Numeric equivalent of Data property Props.InitialValue, a String (default = 0).
ParsedInfo.
Range.
Maximum
 Double
 RO
 Numeric equivalent of Data property Props.Range.Maximum, a String (default = inf).
ParsedInfo.
Range.
Minimum
 Double
 RO
 Numeric equivalent of Data property Props.Range.Minimum, a String (default = -inf).
PortNumber
 Integer
 RO
 Port index number for this data (default = 1).
Props.
Range.
Maximum
 String
 RW
 Maximum value (default = '') that this data can have during execution or simulation of the state machine. Equivalent to entering value in the Max column for this data in Explorer or the Max field in the properties dialog for this data.
Props.
Range.
Minimum
 String
 RW
 Minimum value (default = '') that this data can have during execution or simulation of the state machine. Equivalent to entering a value in the Min column for this data in Explorer or the Min field in the properties dialog for this data.
Props.
InitialValue
 String
 RW
 If the source of the initial value for this data is the Stateflow data dictionary, this is the value used (default = 0) . Equivalent to entering this value in the InitVal column for this data in the Explorer or similar field in the properties dialog for this data.
Props.
Array.
Size
 String
 RW
 Specifying a positive value for this property specifies that this data is an array of this size (default = 0). Equivalent to entering a positive value in the Size column for this data in the Explorer or in the Sizes field of the properties dialog for this data.
Props.
Array.
FirstIndex
 String
 RW
 Index of the first element of this data (default = 0) if it is an array (that is, Props.Array.Size > 1) . Equivalent to entering a value of zero or greater in the First Index field of the properties dialog for this data.
SaveToWorkspace
 Boolean
 RW
 If set to true (default = false), this data is saved to the MATLAB workspace. Setting this property to true is equivalent to selecting the ToWS column entry for this data in the Explorer or selecting the Save final value to base workspace field in the properties dialog for this data.
Scope
 Enum
 RW
 Scope of this data. Allowed values vary with the object containing this data.
The following apply to any data object:
  • 'LOCAL_DATA' (Local, default)
  • 'CONSTANT_DATA' (Constant)
  • 'OUTPUT_DATA' (Output to Simulink)
The following apply to data for machines only:
  • 'IMPORTED_DATA' (Exported)
  • 'EXPORTED_DATA' (Imported)
The following apply to data for charts only:
  • 'INPUT_DATA' (Input to Simulink)
The following apply to data for charts and functions only:
  • 'TEMPORARY_DATA' (Temporary)
The following apply to data for functions only:
  • 'FUNCTION_INPUT_DATA' (Input Data)
  • 'FUNCTION_OUTPUT_DATA' (Output Data)
Above values are equivalent to entering the value shown in parentheses in the Scope field of the properties dialog or the Explorer for this data.
Tag
 Any Type
 RW
 Holds data of any type for this Data object (default = []).
Units
 String
 RW
