i have vector [0 0 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 ]
from this i have to extract 5 vectors which are;
[0 0 0 1 2 3]
[1 2 3 4 5 6]
[4 5 6 7 8 9]
[7 8 9 10 11 12]
[10 11 12 13 14 15]
how can write code for this.

Instead of generating a bunch of loose vectors, it's often better to just use a matrix:
A = [0 0 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15];
B = repelem(reshape(A,3,[]),1,2);
B = reshape(B(:,2:end-1),6,[]).'

Well then I guess you can make a bunch of vectors then.
A = [0 0 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15];
myfirst6x1vector = A(1:6)
mysecond6x1vector = A(4:9)
mythird6x1vector = A(7:12)
myfourth6x1vector = A(10:15)
myfifth6x1vector = A(13:18)
