Summary: We present a new block method for solving large nonsymmetric linear systems of equations with multiple right-hand sides. We first give the matrix polynomial interpretation of the classical block biconjugate gradient (Bl-BCG) algorithm using formal matrix-valued orthogonal polynomials.

Keywords: block Krylov subspace, block methods, Lanczos method, multiple right-hand sides, nonsymmetric linear systems
