Quadratic form minimum.


(Quadratic form minimum) Suppose the matrix MATH is symmetric and positive definite. We consider the problem

MATH The problem ( Quadratic form minimum ) always have a unique solution, see the proposition ( Unbounded existence result ). In addition, if MATH then

MATH (Connection between SLA and minimization)
Indeed, MATH In addition, we have MATH see the formula ( Error and residual ).
