physionetdb

    function varargout=physionetdb(varargin)

     db_list=physionetdb(db_name,DoBatchDownload,webBrowserFlag)

     Lists all the available databases at PhysioNet
     (http://physionet.org/physiobank/) or list all available signal in a database.
     Users can read the signals (waveforms) or annotations (labels) using the WFDB
     App Toolbox's functions such as RDSAMP. Options are

     Optional Input Parameters:
     db_name
              String specifying the datbase to query for available signals.
              If left empty (default) a list of available database names is
              returned. NOTE: Some databases (such as 'mimic2db') have a huge
              number of records so that querying the records in the database
              can take a long time.

     DoBatchDownload
              If 'db_name' is present, setting this flag to true
              (DoBatchDownload=1), will download all records of the database
              db_name to a subdirectory in the current directory called
              'db_name'. Default is false. Note: requires that the user have
              write permission to the current directory.

              NOTE: This function currently does not perform any checksum in order
              to verify that the files were downloaded properly.

     webBrowserFlag
              Boolean. If true, displays database information in MATLAB's
              web browser (default = 0).

     Output Parameters
     db_list -(Optional) Cell array list of elements. If an output
              is not provided, results are displayed to the screen.
              The returned valued are either a list of database names to query
              (if db_name is empty), or a list of available signals that can
              be read via RDSAMP (if db_name is a name of a valid database as
              given by the return list when db_name is empty).
