A block version of BiCGSTAB for linear systems with multiple right-hand sides
Electronic transactions on numerical analysis, Tome 16 (2003), pp. 129-142
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.
