1Indicating indexes between ([]) retrieves corresponding values in Matlab. 
2array_borders=array([1 end])
3As end defines size of the array, retrieve first and last border values of array
5Retrieve only second elements of array, from secon with 2 step iteration 
6increase until end of array.
8Retrieve only first 3 elements of array.
