List names of top-level data logging objects in Simulink ModelDataLogs data
log
log.who tsarray.who log.who('systems') log.who('all')
Note
To list names of top-level data logging objects in Dataset format,
use find
The ModelDataLogs class is supported
for backwards compatibility. Starting in R2016a, you cannot log data
in the ModelDataLogs format. Signal logging
uses the Dataset format. In R2016a or later,
when you open a model from an earlier release that had used ModelDataLogs format,
the model simulated in use Dataset format.
You can convert signal logging data from ModelDataLogs to Dataset format.
Converting to Dataset format makes it easier
to post-process with other logged data (for example, logged states),
which can also use Dataset format. For
more information, see Convert Logged Data to Dataset Format.
If you have legacy code that uses the ModelDataLogs API,
you can encounter situations that require updates to your code or
model. See Migrate Scripts That Use Legacy ModelDataLogs API.
log.who or who(log) lists
the names of the top-level signal logging objects contained by log,
where log is the handle of a Simulink.ModelDataLogs object
name.
tsarray.who or who(tsarray) lists
the names of Simulink.TimeSeries objects contained
by the Simulink.TsArray object named tsarray.
log.who('systems') or who(log,
'systems') lists the names of all signal logging objects
contained by log except for Simulink.Timeseries objects
stored in Simulink.TsArray objects contained by log.
log.who('all') or who(log,
'all') lists the names of all the Simulink.Timeseries objects
contained by the Simulink.ModelDataLogs, Simulink.TsArray,
or Simulink.SubsysDataLogs object named log.
For information about other uses of who, use the help function for who in the MATLAB® Command Window.
Tip
To get the names of Dataset variables in
the MAT-file, using the Simulink.SimulationData.DatasetRef.getDatasetVariableNameswho or whos functions.
find | Simulink.ModelDataLogs | Simulink.SimulationData.DatasetRef.getDatasetVariableNames | Simulink.SubsysDataLogs | Simulink.Timeseries | Simulink.TsArray | unpack | whos
