List names and types of top-level data logging objects in Simulink data log
log.whos tsarray.whos log.whos('systems') log.whos('all')
log.whos or whos(log) lists the names and types of the top-level signal logging objects contained by log, where log is the handle of a Simulink.ModelDataLogs object name.
tsarray.whos or whos(tsarray) lists the names and types of Simulink.TimeSeries objects contained by the Simulink.TsArray object named tsarray.
log.whos('systems') or whos(log, 'systems') lists the names and types of all signal logging objects contained by log except for Simulink.Timeseries objects stored in Simulink.TsArray objects contained by log.
log.whos('all') or whos(log, 'all') lists the names and types of all the Simulink.Timeseries objects contained by the Simulink.ModelDataLogs, Simulink.TsArray, or Simulink.SubsysDataLogs object named log.
