How do i convert this data

I have a data as like A=[1 2 3;4 5 6;7 8 9] How can i convert it to B=[1 2 3 4 5 6 7 8 9]

A=1 2 3

4 5 6

7 8 9

B=horzcat(A(1,:),A(2,:),A(3,:)) i made this. its ok but my original data has too large dimension. i cant write as like this one by one.

Is there anybody help about that ?
