Abstract:
In this paper, an operator iterative procedure for constructing of the orthogonal projection of a vector on
a given subspace is proposed. The algorithm is based on the Euclidean ortogonalization of power sequences of
a special linear transformation generated by the original subspace. For consistent systems of linear algebraic
equations, a numerical method based on this idea is proposed. Numerical results are presented.
Key words:
numerical methods, linear algebra, orthogonal projectors, Kaczmarz method, Krylov subspaces.
