Find the equation satisfied by the squares of the singular values of the matrix associated with the following over-determined set of equations: 2x + 3y + z = 0 x-y-z = 1 2x+y = 0 2y + z = −2. Show that one of the singular values is close to zero. Determine the two larger singular values by an appropriate iteration process and the smallest one by indirect calculation.
