| 37 | 1 | equemene | <B>HPL_dlaswp02N</B> |
| 38 | 1 | equemene | packs scattered rows of an array A into workspace W. |
| 39 | 1 | equemene | The row offsets in A are specified by LINDXA. |

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