CPXXbinvrow and CPXbinvrow
The routine CPXXbinvrow/CPXbinvrow
computes the i-th row of the basis
inverse.
int CPXXbinvrow( CPXCENVptr env, CPXCLPptr lp, CPXDIM i, double * y )
int CPXbinvrow( CPXCENVptr env, CPXCLPptr lp, int i, double * y )
Description
This is an advanced routine. Advanced routines typically demand a thorough understanding of the algorithms used by CPLEX. Thus they incur a higher risk of incorrect behavior in your application, behavior that can be difficult to debug. Therefore, the team encourages you to consider carefully whether you can accomplish the same task by means of other Callable Library routines instead.
The routine CPXXbinvrow/CPXbinvrow
computes the i-th row of the basis
inverse.
Arguments
- env
-
The pointer to the CPLEX environment, as returned by
CPXXopenCPLEX/CPXopenCPLEX
. - lp
-
A pointer to the CPLEX LP problem object, as returned by
CPXXcreateprob/CPXcreateprob
. - i
- An integer that specifies the index of the row to be computed.
- y
- An array containing the i-th row of Binv (the inverse of the matrix B). The array must be of length at least equal to the number of rows in the problem.
