please explain the X= [ones(1,2) 2 ones(1,1) 2 ones(1,2) 1];

line of code. I understand that it is creating 1 by 2 array of ones. But what is the significance of 2 ones(1,1) and so on.

It depends on the requirement of what array you want. If you see that line generates:

[1 1 2 1 2 1 1 1]

The array has 2 in 3rd, 4th position. So 2 is used. The same can also be generated using:

 X = ones(1,8) ;
 X([3 5]) = 2
