How to combine n cell arrays into one giant one?

Hello,

I have a 12-by-190 cell array dataset, each contains either a 1-by-504 cell array or a 1-by-336 cell array. Each of these cell array contains a vector of size of either 600-by-1 or 300-by-1.

As for labels, I have a 12-by-190 cell arrays that each cell contains either a 1-by-504 cell array or a 1-by-336 cell array.

I'd like to concatenate all of the cells together into one giant cells (or preferably a giant matrix) and a corresponding array of labels.

How can I do that?

Thanks in advance

I think you need to loop a bit since you have cells of cells. Let A and B are ur outer cell matrices, data and labels

    % Try this
NA=[];
NB =[];
 for i = length(A)
 a = [A{i}{:}];
 b = [B{i}{:}];
NA = [NA,a(:)];
NB = [NB,b(:)];
end

if you get an error try this instead [NA;a(:)];

Thank you so much for your response. I added one more loop to go over 12 cells but it seems it takes forever

NA=[];
NB =[];
 for i = 1: size(A,1)
     for j = 1: size(A,2)
 a = [A{i}{:}];
 b = [B{i}{:}];
NA = [NA;a(:)];
NB = [NB;b(:)];
     end
 end

any idea? Moreover NA = [NA,b(:)] gives me error and using ";" doesn't make sense with my data.

Thanks again
