CPXgetobj

public int CPXgetobj(CPXCENVptr env, CPXCLPptr lp, double * obj, int begin, int end)
Definition file: cplex.h

The routine CPXgetobj accesses a range of objective function coefficients of a CPLEX problem object. The beginning and end of the range must be specified.

Example

 status = CPXgetobj (env, lp, obj, 0, cur_numcols-1);

Parameters:

env

A pointer to the CPLEX environment as returned by CPXopenCPLEX.

lp

A pointer to a CPLEX problem object as returned by CPXcreateprob.

obj

An array where the specified objective coefficients are to be returned. This array must be of length at least (end - begin + 1). The objective function coefficient of variable j is returned in obj[j - begin].

begin

An integer indicating the beginning of the range of objective function coefficients to be returned.

end

An integer indicating the end of the range of objective function coefficients to be returned.

Returns:

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