how to use a 6-D matrix to store a cell element in this case

Dear Friends,

 JJM=cell(length(X1),1);
 parfor ii=1:length(X1)
     for kk=1:length(X2)
         for jj=1:length(X3)
             for mm=1:length(X4)
                 for nn=1:length(X5)
                     for qq=1:length(X6)
                         V=[X1(ii),X2(kk),X3(jj),X4(mm),X5(nn),X6(qq)]; 
                         JJM{ii}(kk,jj,mm,nn,qq)=objfun(V);
                     end
                 end
             end
         end
     end
 end

As I shown in the above code, JJM is a cell element(11 x 5-D), after the calculation, I want to use a 6-D (11 x 11 x 11 x 11 x 11 x 11) matrix to store the cell element, how can I do this? I mean if to use for-loop, it will be

 for ii=1:numel(JJM)
 JJM1(ii,:,:,:,:,:) =JJM{ii};
 end

however, I try to use it, but there is error message, I also try

 JJM1 = reshape((cell2mat(JJM))',[size(JJM{1}) numel(JJM)]);

it can't work too, is there anyone can help me? thanks
