CPXgetdj

int CPXPUBLIC CPXgetdj(CPXCENVptr env, CPXCLPptr lp, double * dj, int begin, int end)

Definition file: cplex.h

Include files: cplex.h

The routine CPXgetdj is used to access the reduced costs for a range of the variables of a linear or quadratic program. The beginning and end of the range must be specified.

Example

 status = CPXgetdj (env, lp, dj, 0, CPXgetnumcols(env,lp)-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`.
dj	An array to receive the values of the reduced costs for each of the variables. This array must be of length at least (`end` - `begin+ 1`). If successful, `dj[0]` through `dj[end-begin]` contain the values of the reduced costs.
begin	An integer indicating the beginning of the range of reduced-cost values to be returned.
end	An integer indicating the end of the range of reduced-costs values to be returned. Example status = CPXgetdj (env, lp, dj, 0, CPXgetnumcols(env,lp)-1);

Returns:

The routine returns zero on success and nonzero if an error occurs.
