function wfdb2mat(varargin)
%
% wfdm2mat(recordName,signaList,N,N0)
%
%    Wrapper to WFDB WFDB2MAT:
%         http://physionet.org/physiotools/wag/wfdb2m-1.htm
%
% Converts a WFDB-compatible signal file to MATLAB/Octave *.mat file.
% The output files are recordNamem.mat and recordNamem.hea. The standard output of 
% WFDB2MAT will be saved in a file recordNamem.info. 
%
% Required Parameters:
%
% recorName
%       String specifying the name of the record in the WFDB path or
%       in the current directory.
%
% Optional Parameters are:
%
% signalList
%       A Mx1 array of integers. Read only the signals (columns)
%       named in the signalList (default: read all signals).
% N
%       A 1x1 integer specifying the sample number at which to stop reading the
%       record file (default read all the samples = N).
% N0
%       A 1x1 integer specifying the sample number at which to start reading the
%       record file (default 1 = first sample).
%
%
% 
% NOTE: 
%       You can use the WFDB2MAT command in order to convert the record data into a *.mat file, 
%       which can then be loaded into MATLAB/Octave's workspace using the LOAD command.        
%       This will load the signal data in raw units (use RDMAT to load the signal in physical units).
