function varargout=wfdbdesc(varargin)


    Wrapper to WFDB WFDBDESC:

 Reads a WFDB record metadata and returns:

       Nx1 vector of structures with the following fields:

       LengthSamples           : Number of samples in record (integer)
       LengthTime              : Duration of record  (String WFDB Time)
       RecordName              : Record name (String)
       RecordIndex             : Record Index (Integer)
       Description             : Signal Description (String)
       SamplingFrequency       : Sampling Frequency w/ Units (String)
       File                    : File name (String)
       SignalIndex             : Zero Based Signal Index (Integer)
       StartTime               : Start Time (String WFDB Time)
       Group                   : Group (Integer)
       AdcResolution           : Bit resolution of the signal (String)
       AdcZero                 : Physical value for 0 ADC (double)
       Baseline                : Physical zero level of signal (Integer)
       CheckSum                : 16-bit checksum of all samples (Integer)
       Format                  : WFDB's Format of the samples (String)
       Gain                    : ADC units per physical unit (String)
       InitialValue            : Value of sample 1 in the signal (Integer)
       IO                      : IO Type  (String)

 Fs   (Optional)
       Nx1 vector of doubles representing the sampling frequency of each
       signal in Hz (if the 'SamplingFrequency' string is parsable).

 sigClass (Optional)
       Nx1 cell array of strings for the corresponding signal class based on
       information from PhysioNet:
       The signal class will be one of the following:
                    BP         blood pressure
                    CO         cardiac output

                    ECG        electrocardiogram
                    EEG        electroencephalogram
                    EMG        electromyogram
                    EOG        electrooculogram
                    Flow       air flow
                    HR         heart rate
                    Noise      for stress testing
                    O2         oxygen
                    PLETH      plethysmogram
                    Pos        body position
                    Resp       respiration
                    Sound      sound
                    ST         ECG ST segment level
                    Status     status of patient or monitor
                    SV         stroke volume
                    Temp       temperature 
                    []         unkown class

 Required Parameters:

       String specifying the name of the record in the WFDB path or
       in the current directory.
