step

System object: comm.IntegrateAndDumpFilter
Package: comm

Integrate discrete-time signal with periodic resets

Syntax

Y = step(H,X)

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) periodically integrates blocks of N samples from the input data, X, and returns the result in Y. N is the number of samples that you specify in the IntegrationPeriod property. X is a column vector or a matrix and the data type is double, single or fixed-point (fi objects). X must have K*N rows for some positive integer K, with one or more columns. The object treats each column as an independent channel with integration occurring along every column. The dimensions of output Y depend on the value you set for the DecimateOutput property.

    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.
