Hi, everyone.
I know that matrix can be constructed via Table or Array, but I want to
construct a matrix from other matrices, how to do it?
For example, suppose I would like to construct a matrix M which is composed
of four matrices, A,B,C,D.  The element corresponding to the first row and
the first column is A, the first row and second column is B...
I used the M={{A,B},{C,D}} and M={A,B,C,D}, but both of them didn't  work.
Thanks for advance.

Best Regards,
