Simulink.SubsysDataLogs

Container for subsystem signal data logs

Description

Note

Before R2016a, the Simulink.SubsysDataLogs class was used in conjunction with the ModelDataLogs logging data format. Starting in R2016a, you cannot log data in the ModelDataLogs format. Signal logging uses the Dataset format.

However, you can use data that was logged in a previous release using ModelDataLogs format.

In releases before R2016a, Simulink® created instances of this class to contain logs for signals in a subsystem models were logged in ModelDataLogs format. Objects of this class have a variable number of properties. The first property, named Name, is the name of the subsystem whose log data this object contains. The remaining properties are signal log or signal log container objects containing the data logged for the subsystem specified by this object's Name property.

For example, suppose you have this logged data from a model run in a release earlier than R2016a:

Simulink.SubsysDataLogs (Gain):
  Name                   elements  Simulink Class

  a                         1      Timeseries
  m                         2      TsArray

You can use either fully qualified log names or the unpack command to access the signal logs contained by a SubsysDataLogs object. For example, to access the amplitudes logged for signal a in the preceding example, you could enter the following at the MATLAB® command line:

data = logsout.Gain.a.Data;

or

>> logsout.unpack('all');
data = a.Data;
Introduced before R2006a
