By transforming nonsymmetric linear systems to the extended skew-symmetric ones, we present the skew-symmetric methods for solving nonsymmetric linear systems with multiple right-hand sides. These methods are based on the block and global Arnoldi algorithm which is formed by implementing orthogonal

The EN method proposed by Eirola and Nevanlinna is extended to a block version for solving nonsymmetric linear systems with multiple right-hand sides. Some basic properties of the block-EN method are shown. We use the deflation technique in the block-EN method to delete linearly dependent vectors in
