how to define a matrx type that each of its element is a matrix as well

Hi, could you help me to achieve the following goal? I would like to define such a matrix, say M=[E1,E2,E3;E4,E5,E6]. And for each element, say E1=[1,2,3;3,2,1]?

See the documentation on Cell Arrays (link).

A matrix cannot contain matrixes as elements. Eitehr use a cell array or a 3D-array, if all sub-matrices have the same size:

A = rand(2, 2);
B = rand(2, 2);
C = rand(2, 2);
D = cat(3, A, B, C)

Now D(:, :, i) is the corresponding "sub-matrix".
