	DIIS helper routine. More...
subroutine	ddx_solvers::makeb (n, nmat, ndiis, e, b)

	jacobi_diis_solver_external WARNING: code duplication is bad, but here it makes a very specific sense. in ddLPB, we are solving a linear system with Jacobi DIIS also to apply the preconditioner. As calling a solver recursively is a terrible idea, we create a copy of jacobi_diis that: More...
