Estimate cross-spectral density

The `dsp.CrossSpectrumEstimator`

System
object™ computes the cross-spectrum density of a signal, using the Welch's averaged
periodogram method.

To implement the cross-spectrum estimation object:

Create the

`dsp.CrossSpectrumEstimator`

object and set its properties.Call the object with arguments, as if it were a function.

To learn more about how System objects work, see What Are System Objects? (MATLAB).

returns a
System
object, `cse`

= dsp.CrossSpectrumEstimator`cse`

, that computes the cross-power spectrum of real or
complex signals using the periodogram method and Welch’s averaged, modified periodogram
method.

returns a `cse`

= dsp.CrossSpectrumEstimator(`Name,Value`

)`dsp.CrossSpectrumEstimator`

System
object, `cse`

, with each specified property name set to the
specified value. Unspecified properties have default values.

To use an object function, specify the
System
object as the first input argument. For
example, to release system resources of a System
object named `obj`

, use
this syntax:

release(obj)
