<H1>Description</H1> |
| 37 |
<B>HPL_dlaswp02N</B> |
| 38 |
packs scattered rows of an array A into workspace W. |
| 39 |
The row offsets in A are specified by LINDXA. |
| 40 |
|
| 41 |
<H1>Arguments</H1> |
| 42 |
<PRE>
|
| 43 |
M (local input) const int |
| 44 |
On entry, M specifies the number of rows of A that should be |
| 45 |
copied into W. M must be at least zero. |
| 46 |
</PRE>
|
| 47 |
<PRE>
|
| 48 |
N (local input) const int |
| 49 |
On entry, N specifies the length of rows of A that should be |
| 50 |
copied into W. N must be at least zero. |
| 51 |
</PRE>
|
| 52 |
<PRE>
|
| 53 |
A (local input) const double * |
| 54 |
On entry, A points to an array of dimension (LDA,N). The rows |
| 55 |
of this array specified by LINDXA should be copied into W. |
| 56 |
</PRE>
|
| 57 |
<PRE>
|
| 58 |
LDA (local input) const int |
| 59 |
On entry, LDA specifies the leading dimension of the array A. |
| 60 |
LDA must be at least MAX(1,M). |
| 61 |
</PRE>
|
| 62 |
<PRE>
|
| 63 |
W0 (local input/output) double * |
| 64 |
On exit, W0 is an array of size (M-1)*LDW+1, that contains |
| 65 |
the destination offset in U where the columns of W should be |
| 66 |
copied. |
| 67 |
</PRE>
|
| 68 |
<PRE>
|
| 69 |
W (local output) double * |
| 70 |
On entry, W is an array of size (LDW,M). On exit, W contains |
| 71 |
the rows LINDXA[i] for i in [0..M) of A stored contiguously |
| 72 |
in W(:,i). |
| 73 |
</PRE>
|
| 74 |
<PRE>
|
| 75 |
LDW (local input) const int |
| 76 |
On entry, LDW specifies the leading dimension of the array W. |
| 77 |
LDW must be at least MAX(1,N+1). |
| 78 |
</PRE>
|
| 79 |
<PRE>
|
| 80 |
LINDXA (local input) const int * |
| 81 |
On entry, LINDXA is an array of dimension M that contains the |
| 82 |
local row indexes of A that should be copied into W. |
| 83 |
</PRE>
|
| 84 |
<PRE>
|
| 85 |
LINDXAU (local input) const int * |
| 86 |
On entry, LINDXAU is an array of dimension M that contains |
| 87 |
the local row indexes of U that should be copied into A and |
| 88 |
replaced by the rows of W. |
| 89 |
