Programming Preamble: Matlab: x= [1 1 1]’ produces a column vector. The ’ indicates transpose. Matlab: n= sqrt (x’*x). Given a column vector, x, this command computes the norm of the vector. Dividing a vector by its norm produces a vector in the same direction as the original vector but of unit length..
