| 43 | 1 | equemene | <B>HPL_dlaswp04N</B> |
| 44 | 1 | equemene | copies M0 rows of U into A and replaces those rows of U |
| 45 | 1 | equemene | with columns of W. In addition M1 - M0 columns of W are copied into |
| 46 | 1 | equemene | rows of U. |

| 49 | 1 | equemene | <PRE>
|
| 50 | 1 | equemene | M0 (local input) const int |
| 51 | 1 | equemene | On entry, M0 specifies the number of rows of U that should be |
| 52 | 1 | equemene | copied into A and replaced by columns of W. M0 must be at |
| 53 | 1 | equemene | least zero. |
| 54 | 1 | equemene | </PRE>
|
| 55 | 1 | equemene | <PRE>
|
| 56 | 1 | equemene | M1 (local input) const int |
| 57 | 1 | equemene | On entry, M1 specifies the number of columns of W that should |
| 58 | 1 | equemene | be copied into rows of U. M1 must be at least zero. |
| 59 | 1 | equemene | </PRE>
|
| 60 | 1 | equemene | <PRE>
|
| 61 | 1 | equemene | N (local input) const int |
| 62 | 1 | equemene | On entry, N specifies the length of the rows of U that should |
| 63 | 1 | equemene | be copied into A. N must be at least zero. |
| 64 | 1 | equemene | </PRE>
|
| 65 | 1 | equemene | <PRE>
|
| 66 | 1 | equemene | U (local input/output) double * |
| 67 | 1 | equemene | On entry, U points to an array of dimension (LDU,N). This |
| 68 | 1 | equemene | array contains the rows that are to be copied into A. |
| 69 | 1 | equemene | </PRE>
|
| 70 | 1 | equemene | <PRE>
|
| 71 | 1 | equemene | LDU (local input) const int |
| 72 | 1 | equemene | On entry, LDU specifies the leading dimension of the array U. |
| 73 | 1 | equemene | LDU must be at least MAX(1,M1). |
| 74 | 1 | equemene | </PRE>
|
| 75 | 1 | equemene | <PRE>
|
| 76 | 1 | equemene | A (local output) double * |
| 77 | 1 | equemene | On entry, A points to an array of dimension (LDA,N). On exit, |
| 78 | 1 | equemene | the rows of this array specified by LINDXA are replaced by |
| 79 | 1 | equemene | rows of U indicated by LINDXAU. |
| 80 | 1 | equemene | </PRE>
|
| 81 | 1 | equemene | <PRE>
|
| 82 | 1 | equemene | LDA (local input) const int |
| 83 | 1 | equemene | On entry, LDA specifies the leading dimension of the array A. |
| 84 | 1 | equemene | LDA must be at least MAX(1,M0). |
| 85 | 1 | equemene | </PRE>
|
| 86 | 1 | equemene | <PRE>
|
| 87 | 1 | equemene | W0 (local input) const double * |
| 88 | 1 | equemene | On entry, W0 is an array of size (M-1)*LDW+1, that contains |
| 89 | 1 | equemene | the destination offset in U where the columns of W should be |
| 90 | 1 | equemene | copied. |
| 91 | 1 | equemene | </PRE>
|
| 92 | 1 | equemene | <PRE>
|
| 93 | 1 | equemene | W (local input) const double * |
| 94 | 1 | equemene | On entry, W is an array of size (LDW,M0+M1), that contains |
| 95 | 1 | equemene | data to be copied into U. For i in [M0..M0+M1), the entries |
| 96 | 1 | equemene | W(:,i) are copied into the row W0(i*LDW) of U. |
| 97 | 1 | equemene | </PRE>
|
| 98 | 1 | equemene | <PRE>
|
| 99 | 1 | equemene | LDW (local input) const int |
| 100 | 1 | equemene | On entry, LDW specifies the leading dimension of the array W. |
| 101 | 1 | equemene | LDW must be at least MAX(1,N+1). |
| 102 | 1 | equemene | </PRE>
|
| 103 | 1 | equemene | <PRE>
|
| 104 | 1 | equemene | LINDXA (local input) const int * |
| 105 | 1 | equemene | On entry, LINDXA is an array of dimension M0 containing the |
| 106 | 1 | equemene | local row indexes A into which rows of U are copied. |
| 107 | 1 | equemene | </PRE>
|
| 108 | 1 | equemene | <PRE>
|
