all_trials_on_date.mat

I am trying to concatenate the table elements of which each of them are double array. How can I do it effectively? I have attached the table for

reference. Basically I am trying to put together all the coordinatetimes values together.

I am not clear what you are trying to concatenate to what, or which dimension you are trying to concatenate over?

Sorry for not being clear enough. I am trying to concatenate by column. I have written this piece of code which worked.

all_trials_on_date_coordinatetimes = [];
all_trials_on_date_xcoordinates = [];
all_trials_on_date_ycoordinates = [];
for idx = 1:length(all_trials_on_date.coordinatetimes)
    all_trials_on_date_coordinatetimes = cat(1, ...
        all_trials_on_date_coordinatetimes, ...
        all_trials_on_date.coordinatetimes{idx, 1});
    all_trials_on_date_xcoordinates = cat(1, ...
        all_trials_on_date_xcoordinates, ...
        all_trials_on_date.xcoordinates{idx, 1});
    all_trials_on_date_ycoordinates = cat(1, ...
        all_trials_on_date_ycoordinates, ...
        all_trials_on_date.ycoordinates{idx, 1});
end
