Abstract
‎This paper deals with a multidimensional variant of the direct incomplete orthogonalization method to solve generalized tensor equations based on the tensor format. With the aid of truncation approach, the incomplete orthogonalization method is a desirable variant of Krylov subspace method for solving tensor equations due to its low computational cost, compared to the other iteration solvers. We investigate also locally orthogonality and some properties of the residual tensors of the proposed method. Finally, we give some numerical experiments to demonstrate the effciency and validity of the presented method.
