| 25 | 1 | equemene | <B>HPL_pdgesvK1</B> |
| 26 | 1 | equemene | factors a N+1-by-N matrix using LU factorization with row |
| 27 | 1 | equemene | partial pivoting. The main algorithm is the "right looking" variant |
| 28 | 1 | equemene | with look-ahead. The lower triangular factor is left unpivoted and |
| 29 | 1 | equemene | the pivots are not returned. The right hand side is the N+1 column of |
| 30 | 1 | equemene | the coefficient matrix. |
