.SH DESCRIPTION |
| 29 |
\fB\&HPL_dlaswp02N\fR |
| 30 |
packs scattered rows of an array A into workspace W. |
| 31 |
The row offsets in A are specified by LINDXA. |
| 32 |
.SH ARGUMENTS |
| 33 |
.TP 8 |
| 34 |
M (local input) const int |
| 35 |
On entry, M specifies the number of rows of A that should be |
| 36 |
copied into W. M must be at least zero. |
| 37 |
.TP 8 |
| 38 |
N (local input) const int |
| 39 |
On entry, N specifies the length of rows of A that should be |
| 40 |
copied into W. N must be at least zero. |
| 41 |
.TP 8 |
| 42 |
A (local input) const double * |
| 43 |
On entry, A points to an array of dimension (LDA,N). The rows |
| 44 |
of this array specified by LINDXA should be copied into W. |
| 45 |
.TP 8 |
| 46 |
LDA (local input) const int |
| 47 |
On entry, LDA specifies the leading dimension of the array A. |
| 48 |
LDA must be at least MAX(1,M). |
| 49 |
.TP 8 |
| 50 |
W0 (local input/output) double * |
| 51 |
On exit, W0 is an array of size (M-1)*LDW+1, that contains |
| 52 |
the destination offset in U where the columns of W should be |
| 53 |
copied. |
| 54 |
.TP 8 |
| 55 |
W (local output) double * |
| 56 |
On entry, W is an array of size (LDW,M). On exit, W contains |
| 57 |
the rows LINDXA[i] for i in [0..M) of A stored contiguously |
| 58 |
in W(:,i). |
| 59 |
.TP 8 |
| 60 |
LDW (local input) const int |
| 61 |
On entry, LDW specifies the leading dimension of the array W. |
| 62 |
LDW must be at least MAX(1,N+1). |
| 63 |
.TP 8 |
| 64 |
LINDXA (local input) const int * |
| 65 |
On entry, LINDXA is an array of dimension M that contains the |
| 66 |
local row indexes of A that should be copied into W. |
| 67 |
.TP 8 |
| 68 |
LINDXAU (local input) const int * |
| 69 |
On entry, LINDXAU is an array of dimension M that contains |
| 70 |
the local row indexes of U that should be copied into A and |
| 71 |
replaced by the rows of W. |
