CPXchgrngval

int CPXPUBLIC CPXchgrngval(CPXCENVptr env, CPXLPptr lp, int cnt, const int * indices, const double * values)
Definition file: cplex.h
Include files: cplex.h

The routine CPXchgrngval is used to change the range coefficients of a set of linear constraints in the CPLEX problem object.

Example

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

Parameters:

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 range 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 rows corresponding to the linear constraints for which range coefficients are to be changed.

values

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

Returns:

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