The model is configured to log the estimation data at the block output port data (see
“Export Signal Data Using Signal Logging” (Simulink) for information about data
logging). The data is stored in the MATLAB workspace as the
Simulink.SimulationData.Dataset object logsout. Because data is the only
logged port, you can access the logged data in the first entry in logsout. The Values
field of that entry is a structure containing four fields.6 Online Frequency Response Estimation
