Events
R2026bAn event is the observation of an instantaneous incident that may change a state variable, an output, and/or the occurrence of other events. When an event occurs, you can create a response by invoking a corresponding action for that event. For example, an entity's entry into a block may invoke an entry action. You can write actions for many events using MATLAB® code or Simulink Function blocks. Each block for which you can create actions has an Event Actions tab. For more information on events and event actions, see Events and Event Actions.
