Does this command indicate that train.mat contains a variable named array?
whos -file train.mat % or whos('-file', 'train.mat')
The train.mat file included in MATLAB does not.
which -all train.mat
Did you expect array to refer to either the variable Fs or the variable y in the train.mat in MATLAB?

ecg_signal = ecg.y(3, :)
But note if you later define ecg to be the data loaded from a different file, one that uses a different variable name, you'd need to use a different field name. The functionality described on this documentation page may be of use to you in that senario.
