** In this comment, I use the notation M* = conj(M), ** In this comment, I use the following notation:
M.T = transpose(M), M' = ctranspose(M), M N = dot(M, N) M* = conj(M),
M.T = transpose(M),
M' = ctranspose(M),
M N = dot(M, N)
This solver uses a symmetrized wave operator M = (L A R) = (L A R).T This solver uses a symmetrized wave operator M = (L A R) = (L A R).T
