Dear All, I am solving a coupled system. One system is AX=B. A, X and B are all real numbers and it is solved with GMRES in petsc. Now I need to solve a second linear system, it can be represented as (A+i*w)*Z=C. i is the imaginary unit. Z and C are also complex numbers.
So the Jacobian matrix of the second system is just A plus a diagonal contribution i*w. I would like solve the second system with GMRES, could petsc handle this? any comments are welcome. Thanks, Feng
