(c) Find the least squares solution to the problem ar₁ = b for the one unknown ₁ where a and b are column vectors of length m. In this way find the least squares approximation for the unknown scalar A to the equations Ax = xx where x is a given m-dimensional vector and A is a given m x m matrix. The result is known as the Rayleigh-quotient approximation for the eigenvalue X given an approximate eigenvector x.
