step
System object: comm.IntegrateAndDumpFilter
Namespace: 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
obj
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. For more information on changing property values, see System Design in MATLAB Using System Objects.
