.SH DESCRIPTION |
| 25 |
\fB\&HPL_dlaswp03N\fR |
| 26 |
copies columns of W into rows of an array U. The |
| 27 |
destination in U of these columns contained in W is stored within W0. |
| 28 |
.SH ARGUMENTS |
| 29 |
.TP 8 |
| 30 |
M (local input) const int |
| 31 |
On entry, M specifies the number of columns of W stored |
| 32 |
contiguously that should be copied into U. M must be at least |
| 33 |
zero. |
| 34 |
.TP 8 |
| 35 |
N (local input) const int |
| 36 |
On entry, N specifies the length of columns of W stored |
| 37 |
contiguously that should be copied into U. N must be at least |
| 38 |
zero. |
| 39 |
.TP 8 |
| 40 |
U (local input/output) double * |
| 41 |
On entry, U points to an array of dimension (LDU,N). Columns |
| 42 |
of W are copied as rows within this array U at the positions |
| 43 |
specified in W0. |
| 44 |
.TP 8 |
| 45 |
LDU (local input) const int |
| 46 |
On entry, LDU specifies the leading dimension of the array U. |
| 47 |
LDU must be at least MAX(1,M). |
| 48 |
.TP 8 |
| 49 |
W0 (local input) const double * |
| 50 |
On entry, W0 is an array of size (M-1)*LDW+1, that contains |
| 51 |
the destination offset in U where the columns of W should be |
| 52 |
copied. |
| 53 |
.TP 8 |
| 54 |
W (local input) const double * |
| 55 |
On entry, W is an array of size (LDW,M), that contains data |
| 56 |
to be copied into U. For i in [0..M), entries W(:,i) should |
| 57 |
be copied into the row or column W0(i*LDW) of U. |
| 58 |
.TP 8 |
| 59 |
LDW (local input) const int |
| 60 |
On entry, LDW specifies the leading dimension of the array W. |
| 61 |
LDW must be at least MAX(1,N+1). |
