Instructions Create a script called script15.m. The script should assume a positive integer n is
assigned in the command window. The script should create an n-by-n matrix Q according to the
following examples: n 1; script15 10 0 1 n 2; script 15 1 0 0 0 0 1 0 0 0 0 20 0 0 0 2 n 4; script 15

Solution
Option 2 is correct. you can create a sub-matrix taking a sub-part of a matrix. You can also select
the elements in the m( th) through n (th) columns, for this we write: a(:,m:n)
In this way, we will get option 2.
