<H1>Description</H1> |
| 35 |
<B>HPL_dlaswp01N</B> |
| 36 |
copies scattered rows of A into itself and into an |
| 37 |
array U. The row offsets in A of the source rows are specified by |
| 38 |
LINDXA. The destination of those rows are specified by LINDXAU. A |
| 39 |
positive value of LINDXAU indicates that the array destination is U, |
| 40 |
and A otherwise. |

<H1>Arguments</H1> |
| 43 |
<PRE>
|
| 44 |
M (local input) const int |
| 45 |
On entry, M specifies the number of rows of A that should be |
| 46 |
moved within A or copied into U. M must be at least zero. |
| 47 |
</PRE>
|
| 48 |
<PRE>
|
| 49 |
N (local input) const int |
| 50 |
On entry, N specifies the length of rows of A that should be |
| 51 |
moved within A or copied into U. N must be at least zero. |
| 52 |
</PRE>
|
| 53 |
<PRE>
|
| 54 |
A (local input/output) double * |
| 55 |
On entry, A points to an array of dimension (LDA,N). The rows |
| 56 |
of this array specified by LINDXA should be moved within A or |
| 57 |
copied into U. |
| 58 |
</PRE>
|
| 59 |
<PRE>
|
| 60 |
LDA (local input) const int |
| 61 |
On entry, LDA specifies the leading dimension of the array A. |
| 62 |
LDA must be at least MAX(1,M). |
| 63 |
</PRE>
|
| 64 |
<PRE>
|
| 65 |
U (local input/output) double * |
| 66 |
On entry, U points to an array of dimension (LDU,N). The rows |
| 67 |
of A specified by LINDXA are be copied within this array U at |
| 68 |
the positions indicated by positive values of LINDXAU. |
| 69 |
</PRE>
|
| 70 |
<PRE>
|
| 71 |
LDU (local input) const int |
| 72 |
On entry, LDU specifies the leading dimension of the array U. |
| 73 |
LDU must be at least MAX(1,M). |
| 74 |
</PRE>
|
| 75 |
<PRE>
|
| 76 |
LINDXA (local input) const int * |
| 77 |
On entry, LINDXA is an array of dimension M that contains the |
| 78 |
local row indexes of A that should be moved within A or |
| 79 |
or copied into U. |
| 80 |
</PRE>
|
| 81 |
<PRE>
|
| 82 |
LINDXAU (local input) const int * |
| 83 |
On entry, LINDXAU is an array of dimension M that contains |
| 84 |
the local row indexes of U where the rows of A should be |
| 85 |
copied at. This array also contains the local row offsets in |
| 86 |
A where some of the rows of A should be moved to. A positive |
| 87 |
value of LINDXAU[i] indicates that the row LINDXA[i] of A |
| 88 |
should be copied into U at the position LINDXAU[i]; otherwise |
| 89 |
the row LINDXA[i] of A should be moved at the position |
| 90 |
-LINDXAU[i] within A. |
