| 16 | 1 | equemene | .SH DESCRIPTION |
| 17 | 1 | equemene | \fB\&HPL_pdgesvK2\fR |
| 18 | 1 | equemene | factors a N+1-by-N matrix using LU factorization with row |
| 19 | 1 | equemene | partial pivoting. The main algorithm is the "right looking" variant |
| 20 | 1 | equemene | with look-ahead. The lower triangular factor is left unpivoted and |
| 21 | 1 | equemene | the pivots are not returned. The right hand side is the N+1 column of |
| 22 | 1 | equemene | the coefficient matrix. |
