The seed method is used for solving multiple linear systems A(i)x(i)=b(i) for 1≤i≤s, where the coefficient matrix A(i) and the right-hand side b(i) are different in general. It is known that the CG method is an effective method for symmetric coefficient matrices A(i). In this paper, the FOM method is employed to solve multiple linear systems when coefficient matrices are non-symmetric matrices. One of the systems is selected as the seed system which generates a Krylov subspace, then the residuals of other systems are projected onto the generated Krylov subspace to get the approximate solutions for the unsolved ones. The whole process is repeated until all the systems are solved.
