Yes,
As I understand it, the result of assigning a new value to some  
elements of x is the vector x with those values changed.
So if you just drop the ";" at the end of the assignment statement  
you will get a print out of all x, while, if you do

x(lower) = 4*x(lower);
x(lower)

you will see only the first two elements.
Matlab behaves the same way
