| 14 | 1 | equemene | * ======= |
| 15 | 1 | equemene | * |
| 16 | 1 | equemene | * XERBLA is an error handler for the LAPACK routines. |
| 17 | 1 | equemene | * It is called by an LAPACK routine if an input parameter has an |
| 18 | 1 | equemene | * invalid value. A message is printed and execution stops. |
| 19 | 1 | equemene | * |
| 20 | 1 | equemene | * Installers may consider modifying the STOP statement in order to |
| 21 | 1 | equemene | * call system-specific exception-handling facilities. |
