CPXXftran and CPXftran

The routine CPXXftran/CPXftran solves By = x and puts the answer in the vector x, where B is the basis matrix.

int  CPXXftran( CPXCENVptr env, CPXCLPptr lp, double * x )

int  CPXftran( CPXCENVptr env, CPXCLPptr lp, double * x )

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 CPXXftran/CPXftran solves By = x and puts the answer in the vector x, where B is the basis matrix.

Arguments

env
The pointer to the CPLEX environment, as returned by CPXXopenCPLEX/CPXopenCPLEX.
lp
A pointer to a CPLEX LP problem object, as returned by CPXXcreateprob/CPXcreateprob.
x
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.
