| 34 | 1 | equemene | <H1>Arguments</H1> |
| 35 | 1 | equemene | <PRE>
|
| 36 | 1 | equemene | M (local input) const int |
| 37 | 1 | equemene | On entry, M specifies the number of rows of the array B and |
| 38 | 1 | equemene | the number of columns of A. M must be at least zero. |
| 39 | 1 | equemene | </PRE>
|
| 40 | 1 | equemene | <PRE>
|
| 41 | 1 | equemene | N (local input) const int |
| 42 | 1 | equemene | On entry, N specifies the number of rows of the array A and |
| 43 | 1 | equemene | the number of columns of B. N must be at least zero. |
| 44 | 1 | equemene | </PRE>
|
| 45 | 1 | equemene | <PRE>
|
| 46 | 1 | equemene | A (local input) const double * |
| 47 | 1 | equemene | On entry, A points to an array of dimension (LDA,M). |
| 48 | 1 | equemene | </PRE>
|
| 49 | 1 | equemene | <PRE>
|
| 50 | 1 | equemene | LDA (local input) const int |
| 51 | 1 | equemene | On entry, LDA specifies the leading dimension of the array A. |
| 52 | 1 | equemene | LDA must be at least MAX(1,N). |
| 53 | 1 | equemene | </PRE>
|
| 54 | 1 | equemene | <PRE>
|
| 55 | 1 | equemene | B (local output) double * |
| 56 | 1 | equemene | On entry, B points to an array of dimension (LDB,N). On exit, |
| 57 | 1 | equemene | B is overwritten with the transpose of A. |
| 58 | 1 | equemene | </PRE>
|
| 59 | 1 | equemene | <PRE>
|
| 60 | 1 | equemene | LDB (local input) const int |
| 61 | 1 | equemene | On entry, LDB specifies the leading dimension of the array B. |
| 62 | 1 | equemene | LDB must be at least MAX(1,M). |
| 63 | 1 | equemene | </PRE>
