System object: dsp.StandardDeviation
Package: dsp

Calculate standard deviation of input

Syntax

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

Description

Y = step(H,X) computes the standard deviation,Y, of input X. The object computes the standard deviation over successive calls to the step method when the RunningStandardDeviation property is true.

Y = step(H,X,R) resets its state based on the value of reset signal R and the ResetCondition property. You can use this option only when the RunningStandardDeviation property is 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.
