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