Xun,
I think you want...
<< LinearAlgebra`MatrixManipulation`
(A = BlockMatrix[{{a, b}, {c, d}}]) // MatrixForm

Hello,
I have something as following:
a = Array[aa, {3, 3}];
b = Array[bb, {3, 3}];
c = Array[cc, {3, 3}];
d = Array[dd, {3, 3}];
A = {{a, b}, {c, d}} (* A consists of four blocks *)
A // MatrixForm
And I want a 6*6 matrix (a list of 6 lists) just as A looks like.
For example, the first row should be
aa[1,1],aa[1,2],aa[1,3],bb[1,1],bb[1,2],bb[1,3]
etc....
How to get it easily?
Many thanks.
Xun
