Output decimated values of input signal


Y = step(H, X)



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) outputs the decimated values, Y, of the input signal X. The System object treats the input matrix Ki-by-N as N independent channels. The System object filters each channel over time and generates a Ko-by-N output matrix. Ko = Ki/M where M represents the decimation factor. The System object supports real and complex floating-point inputs.


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 (MATLAB) 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.
