CPXchgrngval

Description

The routine CPXchgrngval() is used to change the range 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 CPXchgrngval (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 range 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 range coefficients are to be changed.

An array of length cnt containing the new values of the range coefficients of the constraints present in indices.

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