This is an advanced routine. Advanced routines typically demand a thorough understanding of the algorithms used by ILOG CPLEX. Thus they incur a higher risk of incorrect behavior in your application, behavior that can be difficult to debug. Therefore, ILOG encourages you to consider carefully whether you can accomplish the same task by means of other Callable Library routines instead.
The routine CPXbinvarow computes the
i-th row of BinvA
where Binv
represents the inverse of the matrix B and juxtaposition indicates matrix
multiplication. In other words, it computes the i-th row of the tableau.
| env | The pointer to the ILOG CPLEX environment, as returned by |
| lp | A pointer to a CPLEX LP problem object, as returned by |
| i | An integer that indicates the index of the row to be computed. |
| z | An array containing the i-th row of BinvA. The array must be of length at least equal to the number of columns in the problem. |
