 % % if u_micro is ordered as [coners(:); bdofs(:); idofs(:); inner(:)]
 % dofid is the idx of u_micro under orignal order
 % usage:
 % if you want to reorder u_micro to orignal order
 % dofid(u_micro)

function [dofid] = reorder_dofs(new_dofs)
    dofs = new_dofs(:);
    dofs(:, 2) = 1:length(dofs);
    dofs = sortrows(dofs, 1);
    dofid = dofs(:, 2);
