step

System object: dsp.SignalSource
Package: dsp

Read one sample or frame of signal

Syntax

Y = step(H)

Description

Y = step(H) outputs one sample or frame of data, Y, from each column of the imported signal. The imported signal is the variable or expression you specify for the Signal property of the SignalSource System object™ H.

    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.
