The Toolbox is compatible with 64-bit MATLAB and GNU Octave on GNU/Linux, Mac OS X, and MS-Windows. To quick start to use offline WFDB Toolbox for Matlab http://physionet.org/physiotools/matlab/wfdb-app-matlab/wfdb-app-toolbox-0-9-6-1.zip  download this file.  Unzip file where you want. When unzip the file, mcode folder will create.  Open MATLAB.  Go where you unzip the file.  Write command line addpath(pwd) Finally write command line again savepath  You can use WFDB Toolbox offline anymore.  [tm,sig]=rdsamp('mitdb/100',1); plot(tm,sig);
