Y = step(H,X)
Y = step(H,X,R)
Y = step(H,X) adds delay to input X to return output Y.
Y = step(H,X,R) adds delay to X , and selectively resets the delay object's state based on the value of reset input R and the value of the ResetCondition property. You can use this option only when you set the ResetInputPort property to true.
Note: The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties and input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object™ issues an error. To change nontunable properties or inputs, you must first call the release method to unlock the object.
