CPXXbtran and CPXbtran

The routine CPXXbtran/CPXbtran solves xTB = yT and puts the answer in y.

int  CPXXbtran( CPXCENVptr env, CPXCLPptr lp, double * y )

int  CPXbtran( CPXCENVptr env, CPXCLPptr lp, double * y )

Description

Warning:

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 CPXXbtran/CPXbtran solves xTB = yT and puts the answer in y. B is the basis matrix.

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.
y
An array that holds the righthand side vector on input and the solution vector on output. The array must be of length at least equal to the number of rows in the LP problem object.

Return

The routine returns 0 (zero) if successful and nonzero if an error occurs.
