Store data for mux or bus signal



Before R2016a, the Simulink.TsArray 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 earlier than R2016a, Simulink® software created instances of this class to contain the data that it logs for a mux or bus signal. Other types of signals were stored in a Simulink.Timeseries.

Objects of the Simulink.TsArray class have a variable number of properties. The first property, called Name, specifies the log name of the logged signal. The remaining properties reference logs for the elements of the logged signal: Simulink.Timeseries objects for elementary signals and Simulink.TSArray objects for mux or bus signals. The name of each property is the log name of the corresponding signal.

For example, suppose you have this logged data from a model run in a release earlier than R2016a that was configured to log in ModelDataLogs format.

Simulink.TsArray (untitled/Bus Creator1):
  Name                   elements   Simulink Class

  x1                        1       Timeseries
  b1                        2       TsArray

The Simulink.ModelDataLogs object, named logsout, contains a Simulink.TsArray object, named b2, that contains the logs for the elements of b2 (that is, the elementary signal x1 and the bus signal b1). Entering the fully qualified name of the Simulink.TsArray object, (logsout.b2) at the MATLAB® command line reveals the structure of the signal log for this model.

You can use either fully qualified log names or the unpack command to access the signal logs contained by a Simulink.TsArray object. For example, to access the amplitudes logged for signal x1 in the preceding example, you can enter the following at the MATLAB command line:

data = logsout.b2.x1.Data;


data = x1.Data;
