MATLAB: Concat and display embedded arrays

concat arrays

Can anyone help me to understand why when I try to concat Array B, I can't see the rows (10) and cols (5).
A = [];
B = [];
for j = 1:10
  for i=1:5
      x=randi(3);
      Ai = x;
      A = [A;Ai];
  end
  B{j} = A';
  B = [B; B{j}];
end
Thanks.

Best Answer

B = [];
for j = 1:10
  A = [];
  for i=1:5
     x=randi(3);
     A=[A;x];
  end
B =[B;A']
end
