CPXbinvcol

int CPXPUBLIC CPXbinvcol(CPXCENVptr env, CPXCLPptr lp, int j, double * x)

Definition file: cplex.h

Note

This is an advanced routine. Advanced routines typically demand a profound 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 CPXbinvcol computes the j-th column of the basis inverse.

Parameters:

env	The pointer to the ILOG CPLEX environment, as returned by `CPXopenCPLEX`.
lp	A pointer to a CPLEX LP problem object, as returned by `CPXcreateprob`.
j	An integer that indicates the index of the column of the basis inverse to be computed.
x	An array containing the j-th column 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.

Returns:

The routine returns zero on success and nonzero if an error occurs.
