how to define matirx series?

Dear community,

I want to define a matirx series whose each element is a matirx. For example,

a1 = randn(2,2);
a2 = randn(2,2);
a3 = randn(2,2);
...
an = randn(2,2);

I want to define

c = [a1, a2, a3, ..., an];

But the operator [] returns a combined matrix.

square bracket returns horizontal concatenation of input argument. i guess you can use a cell array

c = {a1,a2,a3};
