how can i combine 4 matrix as 1

for example A=[1 2],B=[3 4],C=[5 6] and D=[7 8] then the resultant matrix E E=[1 2 3 4

   5 6 7 8]
it means it becomes 2*4 matrix

You need to horizontally concatenate the vectors, then use the reshape function:

A=[1 2];
B=[3 4];
C=[5 6];
D=[7 8];

E = reshape([A B C D], [], 2).'

E =
     1     2     3     4
     5     6     7     8
