#+NAME: qmckl_adjugate_safe_args
| Variable | Type | In/Out | Description |
|--------------+-----------------+--------+------------------------------------------------|
| ~context~ | ~qmckl_context~ | in | Global state |
| ~n~ | ~int64_t~ | in | Number of rows and columns of the input matrix |
| ~A~ | ~double[][lda]~ | in | Array containing the $n \times n$ matrix $A$ |
| ~size_max_A~ | ~int64_t~ | in | Size of the matrix $A$ |
| ~lda~ | ~int64_t~ | in | Leading dimension of array ~A~ |
| ~B~ | ~double[][ldb]~ | out | Adjugate of $A$ |
| ~size_max_B~ | ~int64_t~ | in | Size of the matrix $B$ |
| ~ldb~ | ~int64_t~ | in | Leading dimension of array ~B~ |
| ~det_l~ | ~double~ | inout | determinant of $A$ |
Requirements:
- ~context~ is not ~QMCKL_NULL_CONTEXT~
- ~n > 0~
- ~lda >= m~
- ~A~ is allocated with at least $m \times m \times 8$ bytes
- ~ldb >= m~
- ~B~ is allocated with at least $m \times m \times 8$ bytes
- ~size_max_A >= m * m~
- ~size_max_B >= m * m~
