Does this command indicate that train.mat contains a variable named array?

whos -file train.mat % or whos('-file', 'train.mat')

  Name          Size             Bytes  Class     Attributes

  Fs            1x1                  8  double              
  y         12880x1             103040  double              

The train.mat file included in MATLAB does not.

which -all train.mat

/MATLAB/toolbox/matlab/audiovideo/train.mat

Did you expect array to refer to either the variable Fs or the variable y in the train.mat in MATLAB?

[Neha Sinha]

With array I wanted to read each row of the Train.mat file. How to read it?

[Steven Lord]

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.
