void | dGetDiagU (SuperMatrix *L, double *diagU) |
-- Auxiliary routine in SuperLU (version 2.0) -- Lawrence Berkeley National Lab, Univ. of California Berkeley. Xiaoye S. Li September 11, 2003
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.
