| <pre> Purpose |
| =======</pre><p> |
| <pre> GetDiagU extracts the main diagonal of matrix U of the LU factorization.</pre><p> |
| <pre> Arguments |
| =========</pre><p> |
| <pre> L (input) SuperMatrix* |
| The factor L from the factorization Pr*A*Pc=L*U as computed by |
| <a class="el" href="dgstrf_8c.html#65a25ed27f2524e9cbc8f6ce8cd22c38">dgstrf()</a>. Use compressed row subscripts storage for supernodes, |
| i.e., L has types: Stype = SLU_SC, Dtype = SLU_D, Mtype = SLU_TRLU.</pre><p> |
| <pre> diagU (output) double*, dimension (n) |
| The main diagonal of matrix U.</pre><p> |
| <pre> Note |
| ==== |
| The diagonal blocks of the L and U matrices are stored in the L |
| data structures. |
