Ran in:
A=[1 2 3 4 5 6 7 8 9 11 12 12 14 15 16 17 18 19 20;1 2 3 4 5 6 7 8 9 11 12 12 14 15 16 17 18 19 20;1 2 3 4 5 6 7 8 9 11 12 12 14 15 16 17 18 19 20]
A = 3×19
1 2 3 4 5 6 7 8 9 11 12 12 14 15 16 17 18 19 20 1 2 3 4 5 6 7 8 9 11 12 12 14 15 16 17 18 19 20 1 2 3 4 5 6 7 8 9 11 12 12 14 15 16 17 18 19 20

B=A(:,[1,6,11]);
C=A;
C(:,[1,6,11])=[];
