Simulink.data.DataConnection

Data source connection

Since R2024a

Description

The Simulink.data.connect function creates a Simulink.data.DataConnection object, which represents a connection to a Simulink data dictionary, model workspace, or base workspace. After you create a Simulink.data.DataConnection object, you can manage the data in that data source using the object functions.

Creation

Create a data connection object using Simulink.data.connect.

Object Functions

`clear`	Remove specified variables from connected data source
`clearAll`	Remove variables from connected data source
`create`	Create object in connected data source
`discardChanges`	Discard data in memory and reload from connected data source
`exist`	Determine whether variable exists in connected data source
`get`	Read variables from connected data source
`getMetadata`	Get metadata for variable or connected data source
`hasUnsavedChanges`	Determine whether connected data source has unsaved data in memory
`isConsistent`	Determine whether variable definitions visible to connected data source are consistent
`rename`	Rename specified variables in connected data source
`reportInconsistency`	Report inconsistent variable definitions
`saveChanges`	Save data in memory for connected data source to disk
`set`	Assign variable in connected data source
`show`	Open and show contents of connected data source in Model Explorer
`who`	List variables that are in connected data source

Read Variable from Data Dictionary

Create a connection to a data dictionary myDictionary. Then read a variable from the Design Data section of the dictionary.
```
dd = Simulink.data.connect('myDictionary.sldd');
a = dd.x
```
```
a = 

    2
```
