  Purpose
 =======

 GetDiagU extracts the main diagonal of matrix U of the LU factorization.

 Arguments
 =========

 L      (input) SuperMatrix*
        The factor L from the factorization Pr*A*Pc=L*U as computed by
        dgstrf(). Use compressed row subscripts storage for supernodes,
        i.e., L has types: Stype = SLU_SC, Dtype = SLU_D, Mtype = SLU_TRLU.

 diagU  (output) double*, dimension (n)
        The main diagonal of matrix U.

 Note
 ====
 The diagonal blocks of the L and U matrices are stored in the L
 data structures.
