The elements of a matrix cannot be a matrix again. But you can insert the elements, such that the array grows:
x = 1:3;
y = 7:9;
insertAt = 1
joined = [x(1:insertAt - 1), y, x(insertAt + 1:end)]
% joined =
% 7 8 9 2 3

Hi,
You can do this with cell arrays
a =cell(3,1);
b = rand(3,1)
b =
0.8147
0.9058
0.1270
a{1} = b
a =
3×1 cell array
{3×1 double}
{0×0 double}
{0×0 double}
