What is an event in MATLAB?
Events are notices that objects broadcast in response to something that happens, such as a property value changing or a user interaction with an application program. Listeners execute functions when notified that the event of interest occurs. Use events to communicate changes to objects.
What is event listener in MATLAB?
The event. listener class defines listener objects. Listener objects respond to a specific event by executing a callback function when the event is triggered. You can use the event. listener class to construct a listener object.
What is the use of EventData in MATLAB?
EventData class is the base class for all data objects passed to listeners. When you trigger an event using the notify handle class method, MATLAB® assigns values to the properties of an event. EventData object and passes that object to the listener callback function (the event handler).
What is a callback function in MATLAB?
A callback is a function that executes in response to some predefined user action, such as clicking on a graphics object or closing a figure window. Associate a callback with a specific user action by assigning a function to the callback property for that user action.
How do you define an inline function in MATLAB?
f = inline( expr , arg1,arg2,…,argN ) constructs an inline function whose input arguments are specified by arg1,arg2,…,argN . Multicharacter symbol names may be used. f = inline( expr , N ) , where N is a scalar, constructs an inline function whose input arguments are x and P1,P2,…,PN .
What does vectorize function do in MATLAB?
Vectorization is one of the core concepts of MATLAB. With one command it lets you process all elements of an array, avoiding loops and making your code more readable and efficient. For data stored in numerical arrays, most MATLAB functions are inherently vectorized.
Why do we use callbacks?
