Try to initialize Y first?
Y = zeros(size_determined_by_your_Data, 6);

Note that log(Data(:,6)) has the same size of Data(:, 6). But diff(log(Data(:, 6))) has one less. If your Data(:, 6) has size of n, then diff(log(Data(:, 6))) has size of n-1. Most likely the error is caused by this difference.
In other words, your Y shall be initialized with this in mind.
