CPXchgrhs

Description

The routine CPXchgrhs() is used to change the right-hand side coefficients of a set of constraints in the CPLEX problem object.

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

int CPXchgrhs (CPXCENVptr env, CPXLPptr lp, int cnt, const int *indices, const double *values);

Arguments

The pointer to the CPLEX environment as returned by CPXopenCPLEX().

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

An integer that indicates the total number of right-hand side coefficients to be changed, and thus specifies the length of the arrays indices and values.

An array of length cnt containing the numerical indices of the rows corresponding to the constraints for which right-hand side coefficients are to be changed.

An array of length cnt containing the new values of the right-hand side coefficients of the constraints present in indices.

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