WebCallbacks are a powerful way to customize the behavior of a Simulink ® model. Use callbacks to execute MATLAB ® code in response to specific actions, such as opening a model or stopping a simulation. Each callback corresponds to a specific action. You specify the MATLAB code that a callback executes. WebSimulink defines in a general way the task of each callback. The S-function is free to perform the task according to the functionality it implements. For example, Simulink specifies that the S-function's mdlOutput method must compute that block's outputs at the current simulation time. It does not specify what those outputs must be. greek gods facts and information
