Compatibility issue with MATLAB R2014a
If one runs:
x = dseries(ones(2,2),'1Y',{'A1'; 'A2'});
y = { 'A1', 'A2'};
x{y{:}}.data(2:end, :)
The result is correct under MATLAB R2020b:
ans =
1 1
But it is incorrect under MATLAB R2014a:
ans =
1
Note that this is not a purely theoretical problem. It causes the failure of tests/smoother2histval/fs2000_simul.mod
under R2014a.
