Filter input with Allpole filter object

Syntax

Y = step(H,X)

Description

Y = step(H,X) filters the real or complex input signal X using the Allpole filter, H, to produce the output Y . When the input data is of a fixed-point type, it must be signed. The Allpole filter object operates on each channel of the input signal independently over successive calls to step method.

    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.
