Decode J1939 Data from MDF Files

Import and decode J1939 data from MDF files in MATLAB® for analysis. The MDF file used in this example was generated from Vector CANoe using the "System Configuration (J1939)" sample. This example also uses the CAN database file, Powertrain_J1939_MDF.dbc, provided with the Vector sample configuration.
