How to combine matrices

I have four matrices say A, B, C and D, all square matrices. I need to create a matrix E with all the elements in Matrices A,B,C and D. Is there a way to do that. Note: A,B,C and D are computed by the program so I can't enter the values to form E

Let A, B, C , D be your matrices of size 2X2...to get E..

E = [A B; C D] ;
