Distance between linear varieties in ℝn. application of an (in)equality by (fan-todd) beesack
Description
The closest point of a linear variety to an external point is found by using the equality case of an Ostrowski’s type inequality. This point is given in a closed form as the quotient of a formal and a scalar Gram determinant. Then the best approximation pair of points onto two linear varieties is obtained, besides its characterization.
