I am trying to save to a file 1channel ECG signal from the file containing structure:
Accelerometer: [5183900×4 table]
Breathing: [1295975×2 table]
ECG: [12959750×2 table]
In order to do that I am using load command to a data variable and then save it with save function with the code:
data=load('dataexported_2023_12_17.mat');
[data] = [data.ECG.EcgWaveform];
save('D:\matlab-pliki\MAT2EDF\dataexported_2023_12_17.txt', 'data','-ascii','-tabs', '-double')
Unfortunately I cannot save teh variable data to a file since the variable type is not supported and I am obtaining empty file.
Could you please enlighten me how to fix the code to save ECG data to a file?

Since the variable you want to save is a table, you can use writetable.
