Option to log time values for simulation

Model Configuration Pane: Data Import/Export


Specify whether to log simulation time data to the specified MATLAB® variable during simulation.

By default, simulation results are returned as a single Simulink.SimulationOutput object. The logging variable you specify for time becomes a property of the SimulationOutput object. To access the logged time data, use dot notation. For example, when you use the default output variable name out and the default time logging variable name tout, access the time data using this code.

tout = out.tout;


on (default) | off

The software logs time data during simulation. By default, the name of the logging variable that contains the time data is tout. To use a different variable name, specify a valid MATLAB variable name in the text box.

The variable must not have a name that matches the name of any object functions or properties of the Simulink.SimulationOutput object.


The software does not log time data during simulation.
