Hi Siddhartha,

The apostrophe is the transpose operator.  What it does in the above 
line is that it turns the row vector into a column vector.  If you use 
single number indexing ("x(2)") and are going to iterate through the x 
vector, it may not matter which you use.  If you use two number indexing 
("x(2,1)") or if you are going to use it for some linear algebra 
operations, then there is a difference between the two.

Have a good day,

Bill
