Example: For an array say x, I want every element in x to have an array. so x(1,1) will have an (m X n) matrix and so on.

Use cell array like this
X=cell(3,3);
X{1,1}=rand(3,2);
X{2,1}=rand(5,7);
and so on

X = {};
K = 0;
while rand() <= 0.93
K = K + 1;
n = randi(50);
X{K} = rand(1,n);
end
There, a cell of indefinite length, with each cell member being of potentially different size. Adapt as needed.

Then don't predefine it. You can either give it a blank cell array as walter said in above post, or you can start with something like this:
x{1,1}=rand(3,2)
x =
[3x2 double]
x{3,5}=rand(4,6)
x =
[3x2 double] [] [] [] []
[] [] [] [] []
[] [] [] [] [4x6 double]
x starts to expand and it grows. However, due to performance issue it is not recommended. But if that's what needed then that's what is needed.
