Syntax

Simulink.data.dataSource.addSource(modelName,nameOfExternalSource)

Description

Simulink.data.dataSource.addSource(modelName,nameOfExternalSource) associates an external data source, such as a MAT file or a data dictionary, to a Simulink® model or a Subsystem File specified by modelName. This allows the model to use the variables and data from these external data sources during simulation, compilation, and other model operations.

You can add one data dictionary and multiple MAT files as external data sources to a model and a Subsystem File.

openExample('subsystem_reference/SubsystemReferenceExample')
Simulink.data.dataSource.addSource("SSREF1","myDictionary.sldd")

The scope of the data is within the boundary of the Subsystem File.
