The routine CPXchgobj is used to change the linear objective coefficients of a set of variables in a CPLEX problem object.

Example

 status = CPXchgobj (env, lp, cnt, indices, values);

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
lp	A pointer to a CPLEX problem object as returned by `CPXcreateprob`.
cnt	An integer that indicates the total number of objective coefficients to be changed, and thus specifies the length of the arrays `indices` and `values`.
indices	An array of length `cnt` containing the numeric indices of the columns corresponding to the variables for which objective coefficients are to be changed.
values	An array of length `cnt` containing the new values of the objective coefficients of the variables specified in `indices`.

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