Acces double inside cell array

I have a 1x88 cell array containing different doubles (1000x1, 452x1 or 1842x1). I created a structure with a field and the 1x88 cell array(J). After compilation, next to the field I see the cell (see picture under) and if I click on the cell I see the double. Is there any way that I can acces the double inside the cell through my code and list it directly next to the field so I don't have to click on the cell anymore? So after this, insted of seeing ''J'' and on the right ''1x1 cell'', I would instead see ''J'' and on the right one of the 3 doubles above.

Here is the code:

for i=1:size(Results,1)
    Measurements(i).Det=struct('J',{J(i)});
end

for i=1:size(Results,1)
    Measurements(i).Det.J=J{i};
end
