Contain all event objects


Property to indicate events in a model object. Read-only array of Event objects.

An event defines an action when a defined condition is met. For example, the quantity of a species may double when the quantity of species B is 100. An event is triggered when the conditions specified in the event are met by the model. For more information, see Events and Events in SimBiology Models.

Add an event to a Model object with the method addevent (model) method and remove an event with the delete method. See Event for more information.

You can view event object properties with the get command and modify the properties with the set command.


Applies toObject: model
Data typeArray of event objects
Data valuesEvent object. The default is [] (empty).


  1. Create a model object, and then add an event object.

    modelObj = sbmlimport('oscillator')
    eventObj = addevent(modelObj, 'time>= 5', 'OpC = 200');
  2. Get a list of properties for an event object.




    MATLAB® displays a list of event properties.
