Several other applications of the scattering framework are presented, including doubling formulas for the error covariance, a change of initial conditions formula, equations for a backwards Markov state model and a new derivation of the Chandrasekhar-type equations for the constant parameter case. The ...
A geometric property of the least squares solution of linear equations We derive an explicit determinantal formula for the least squares solution of an overdetermined system of linear equations. From this formula it follows th... Ben-Tal, A,Teboulle, M - 《Linear Algebra & Its Applications》 被...
