Description

Simulink.data.dataSource.removeSource(modelName,nameOfExternalSource) removes an external data source, such as a MAT file or a data dictionary, that is associated with the Simulink^® model or Subsystem File specified by modelName. When you remove an external data source, the model no longer has access to the variables and data contained within the specified external file. The function does not delete the file.
