step

System object: dsp.Mean
Package: dsp

Mean value

Syntax

Y = step(H,X)
Y = step(H,X,R)

Description

    Note:   Starting in R2016b, instead of using the step method to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example, y = step(obj,x) and y = obj(x) perform equivalent operations.

Y = step(H,X) computes the mean of X. When you set the RunningMean property to true, Y corresponds to the mean successive calls to the step method.

Y = step(H,X,R) resets the computation of the running mean based on the value of the reset signal, R, and the ResetCondition property. To enable this type of processing, set the RunningMean property to true and the ResetInputPort property to true.

    Note:   H specifies the System object on which to run this step method.

    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.
