摘要：

In this paper we construct the block skew-symmetric methods for solving nonsymmetric linear systems with multiple right-hand sides systems. These methods are based on the block arnoldi algorithm which is formed by implementing orthogonal projections of the initial matrix residual onto a matrix Krylov subspace.
