摘要: In algorithms for linear algebraic computations there are a fairly small number of basic operations which generally responsible significant percentage the total execution time. We mention particularly dot product operation, ω := xTy, elementary vector y :=αx+y, and euclidean norm, η = (xTx)1/2.
