+! This subroutine changes the storage pattern of a two-d matrix
+!  - Usually element matrix in easifem are stored in `FMT_DOF`
+!  - Global matrices/tanmat, however, are stored in `FMT_Nodes`
+!  - This subroutine is, therefore, in settings or adding values in
+! [[SparseMatrix_]].
+!
+! > This subroutine converts changes the storage format of dense matrix.
+! Usually, elemental finite element matrix is stored in `DOF_FMT`, and global
+! matrix/ tanmat, may be stored in `Nodes_FMT`.
+!
+!@note
+! All dof should have the same order of interpolation, therefore,
