<H1>Description</H1> |
| 29 |
<B>HPL_dlaswp00N</B> |
| 30 |
performs a series of local row interchanges on a matrix |
| 31 |
A. One row interchange is initiated for rows 0 through M-1 of A. |
| 32 |
|
| 33 |
<H1>Arguments</H1> |
| 34 |
<PRE>
|
| 35 |
M (local input) const int |
| 36 |
On entry, M specifies the number of rows of the array A to be |
| 37 |
interchanged. M must be at least zero. |
| 38 |
</PRE>
|
| 39 |
<PRE>
|
| 40 |
N (local input) const int |
| 41 |
On entry, N specifies the number of columns of the array A. |
| 42 |
N must be at least zero. |
| 43 |
</PRE>
|
| 44 |
<PRE>
|
| 45 |
A (local input/output) double * |
| 46 |
On entry, A points to an array of dimension (LDA,N) to which |
| 47 |
the row interchanges will be applied. On exit, the permuted |
| 48 |
matrix. |
| 49 |
</PRE>
|
| 50 |
<PRE>
|
| 51 |
LDA (local input) const int |
| 52 |
On entry, LDA specifies the leading dimension of the array A. |
| 53 |
LDA must be at least MAX(1,M). |
| 54 |
</PRE>
|
| 55 |
<PRE>
|
| 56 |
IPIV (local input) const int * |
| 57 |
On entry, IPIV is an array of size M that contains the |
| 58 |
pivoting information. For k in [0..M), IPIV[k]=IROFF + l |
| 59 |
implies that local rows k and l are to be interchanged. |
