Block variants of the COCG and COCR methods for solving complex symmetric linear systems with multiple right-hand sides

Xian-Ming Gu, Bruno Carpentieri, Ting-Zhu Huang +1

In the present study, we establish two new block variants of the Conjugate Orthogonal Conjugate Gradient (COCG) and the Conjugate A-Orthogonal Conjugate Residual (COCR) Krylov subs…
