      WaveForm DataBase (WFDB) Toolbox

    This is a set of MATLAB functions and wrappers for reading, writing, and processing
    files in the formats used by PhysioBank databases (among others).
    The WFDB Toolbox has support for reading public PhysioNet databases directly from
    web. This feature allows your code to analyze a wide range of physiological
    signals available from PhysioBank without the need to download entire
    records and to store them locally. This toolbox is distributed under the LGPL
    license (see LICENSE.txt file in this directory). For more informationa about the
    toolbox please go to: http://www.physionet.org
