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

In addition, some of these functions use binary executables compiled
from open-source third-party code contributed to PhysioNet. When using
these functions on your work, please look at the help for that function
in order find out how to credit the original paper and authors.
