Description
The routine CPXgetobj() is used to access a range of objective function coefficients of a CPLEX LP problem object. The beginning and end of the range must be specified.Return Value
The routine returns a zero on success, and a nonzero if an error occurs.Synopsis
int CPXgetobj (CPXENVptr env,
CPXLPptr lp,
double *obj,
int begin,
int end);
CPXENVptr envThe pointer to the CPLEX environment as returned by one of the
CPXopenCPLEX routines.
CPXLPptr lpA pointer to a CPLEX LP problem object as returned by
CPXcreateprob().
double *objAn 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 will be returned in obj[j - begin].
int beginAn integer indicating the beginning of the range of objective function coefficients to be returned.
int endAn integer indicating the end of the range of objective function coefficients to be returned.
status = CPXgetobj (env, lp, obj, 0, cur_numcols-1);
