Pradeep - if you want to copy the first three elements of a into b, then just do
a = [22 23 43 0 0 0 0];
b = a(:,1:3);
In the above, since a is a row vector, we want to copy the first three elements (columns) of a. Try it and see what happens!

What if I need the first two elements and the fourth and fifth elements?
