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