    Description

    The Simulink.data.connect function creates a Simulink.data.DataConnection object, which represents a connection to the Design Data section of a Simulink® data dictionary, a MAT file, a model workspace, or the 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 by using Simulink.data.connect.

    Object Functions

    clearRemove specified variables from connected data source
    clearAllRemove variables from connected data source
    createCreate object in connected data source
    discardChangesDiscard data in memory and reload from connected data source
    existDetermine whether variable exists in connected data source
    getRead variables from connected data source
    getMetadataGet metadata for variable or connected data source
    hasUnsavedChangesDetermine whether connected data source has unsaved data in memory
    isConsistentDetermine whether variable definitions visible to connected data source are consistent
    renameRename specified variables in connected data source
    reportInconsistencyReport inconsistent variable definitions
