arraycellconvert

hello everybody how I can convert this cell to array such that I want each element in cell in row in array
ex = {[1,2,4,5,7,11,12],[1,3,4,5,7,11,12],[1,2,4,6,5,7,11,12],[1,3,4,6,5,7,11,12],[1,2,4,5,8,13,7,11,12],[1,3,4,5,8,13,7,11,12],[1,2,4,6,5,8,13,7,11,12],[1,3,4,6,5,8,13,7,11,12]};

Is this kind of what you are looking for?

ex = {[1,2,4,5,7,11,12],[1,3,4,5,7,11,12],[1,2,4,6,5,7,11,12],[1,3,4,6,5,7,11,12],[1,2,4,5,8,13,7,11,12],[1,3,4,5,8,13,7,11,12],[1,2,4,6,5,8,13,7,11,12],[1,3,4,6,5,8,13,7,11,12]};

n=numel(ex);
N=zeros(n,1);
for i=1:n
    N(i)=numel(ex{i});
    ex{i}=ex{i}(:)';
end

if min(N)<max(N)
    dN=max(N)-N;        
    for i=1:n
        if dN(i)>0
            ex{i}=cat(2,ex{i},nan(1,dN(i)));
        end
    end
end
ex=cell2mat(ex(:));

disp(ex)
