      Focusing on advanced methods for solving linear systems, the book explores approximate solutions using Krylov subspace techniques, particularly FOM and GMRES, along with their various implementations. It addresses the common challenge of finding solutions for systems with multiple right-hand sides, highlighting the limitations of existing literature. By introducing a Flexible Block GMRES technique utilizing Householder orthogonalization, this work fills a significant gap, offering new insights and methodologies for researchers and practitioners in numerical linear algebra.
