the finite elemente method people did not bother to check this
Line 6:
Other extensions of multigrid include techniques where no PDE and no geometrical problem background is used to construct the multilevel hierarchy. Such '''algebraic multigrid methods''' (AMG) construct their hierarchy of operators directly from the system matrix and thus become true black-box solvers for [[sparse matrices]].
 
The [[finite elemente method]] becomes multigrid by choosing linear [[wavelets]] as the basis.
