@Ashis Pandey Please format your code. And then ask the question. Your question is not clear.

Here!

The watermarked part is: Record_result = vtrigU.vtrigU.GetRecordingResult(vtrigU.SignalCalibration.DEFAULT_CALIBRATION);

BR_response =ifft(mean(H.*Smat),Nfft,2);

Everything that starts with vtrigU is a function that is being supplied by the ActiveX interface DLL supplied by the manufacturer. vtrigU.SignalCalibration.DEFAULT_CALIBRATION does not mean anything special to MATLAB: it just means that the vtrigU ActiveX object should be told to perform the SignalCalibration action, and that the resulting object should be told to perform the DEFAULT_CALIBRATION action.

These have no inherent meaning to MATLAB; they do whatever the ActiveX control has configured. As far as MATLAB is concerned, it could have been vtrigU.Gort.Klaatu.Barada.Nikto
