https://www.mathworks.com/help/signal/ug/classify-ecg-signals-using-long-short-term-memory-networks.html#ClassifyECGSignalsUsingLSTMNetworksExample-1 I am trying to work on this project but I can’t load PhysionetData. I downloaded the dataset from physionet as a .mat and I am also having trouble about uploading the dataset to MATLAB.

I tried to upload but I ended up with uploading only one ECG signal I don’t know how to upload al of them.
