CPXgetobj

int CPXPUBLIC CPXgetobj(CPXCENVptr env, CPXCLPptr lp, double * obj, int begin, int end)

Definition file: cplex.h

Include files: cplex.h

The routine CPXgetobj is used to access 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 on success and nonzero if an error occurs.
