System object: comm.IntegrateAndDumpFilter
Integrate discrete-time signal with periodic resets
Y = step(H,X)
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: 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.
