In general you can use blkdiag.
A=[1 2 3 6 ];
B=[4 5 5 6 9 8 7 6 9 6 8 6 9];
D=[4 1 2 3 5 68 9 6 9 6 9 6 9 6 9 63 45 82 85 96 74 52 63 10 30 23 65 6 66 33 66 ];
E=[5 4 6 5 4 8 9 6 9 6 8 6];
F=[4 8 9 7 8 6 9 6 8 2 21 3 6 56 36];
G=[7 8 9 9 6 8 6 45 25 33 66 33 14 25 36 36 12];
result = blkdiag(A, B, D, E, F, G).'
result = 92×6
1 0 0 0 0 0 2 0 0 0 0 0 3 0 0 0 0 0 6 0 0 0 0 0 0 4 0 0 0 0 0 5 0 0 0 0 0 5 0 0 0 0 0 6 0 0 0 0 0 9 0 0 0 0 0 8 0 0 0 0
