The WFDB Toolbox for MATLAB/Octave is a collection of functions for reading, writing, and processing physiologic signals in the formats used by PhysioNet (see README for details).
%Example
N=5000;
gqrs('mitdb/100',N);
ann=rdann('mitdb/100','qrs',[],N);
[tm,sig]=rdsamp('mitdb/100',[],N);
plot(tm,sig(:,1));hold on;grid on
plot(tm(ann),sig(ann,1),'ro')
Variable ann ends up being a Nx5 matrix. It looks like the first column are the detections and the rest seems to be some additional information on each beat. However I was not sure.
I am running on a Ubuntu with Matlab 2017a (which I know is not supported). Is anybody else having this problem?
