| 22 | 1 | equemene | .SH DESCRIPTION |
| 23 | 1 | equemene | \fB\&HPL_dlacpy\fR |
| 24 | 1 | equemene | copies an array A into an array B. |
| 25 | 1 | equemene | .SH ARGUMENTS |
| 26 | 1 | equemene | .TP 8 |
| 27 | 1 | equemene | M (local input) const int |
| 28 | 1 | equemene | On entry, M specifies the number of rows of the arrays A and |
| 29 | 1 | equemene | B. M must be at least zero. |
| 30 | 1 | equemene | .TP 8 |
| 31 | 1 | equemene | N (local input) const int |
| 32 | 1 | equemene | On entry, N specifies the number of columns of the arrays A |
| 33 | 1 | equemene | and B. N must be at least zero. |
| 34 | 1 | equemene | .TP 8 |
| 35 | 1 | equemene | A (local input) const double * |
| 36 | 1 | equemene | On entry, A points to an array of dimension (LDA,N). |
| 37 | 1 | equemene | .TP 8 |
| 38 | 1 | equemene | LDA (local input) const int |
| 39 | 1 | equemene | On entry, LDA specifies the leading dimension of the array A. |
| 40 | 1 | equemene | LDA must be at least MAX(1,M). |
| 41 | 1 | equemene | .TP 8 |
| 42 | 1 | equemene | B (local output) double * |
| 43 | 1 | equemene | On entry, B points to an array of dimension (LDB,N). On exit, |
| 44 | 1 | equemene | B is overwritten with A. |
| 45 | 1 | equemene | .TP 8 |
| 46 | 1 | equemene | LDB (local input) const int |
| 47 | 1 | equemene | On entry, LDB specifies the leading dimension of the array B. |
| 48 | 1 | equemene | LDB must be at least MAX(1,M). |
