Description

Low level interface function to the IBM ILOG CPLEX function CPXnewcols. Consult the IBM ILOG CPLEX documentation for more detailed information.

Usage

newColsCPLEX(env, lp, ncols,
             obj = NULL, lb = NULL, ub = NULL,
             xctype = NULL, cnames = NULL)

Arguments

env

An object of class "'>cplexPtr" as returned by openEnvCPLEX. This is basically a pointer to an IBM ILOG CPLEX environment.

lp

An object of class "'>cplexPtr" as returned by initProbCPLEX. This is basically a pointer to an IBM ILOG CPLEX problem object.

ncols

Number of variables to add.

obj

Objective function coefficients.

lb

Lower bounds on the new variables.

ub

Upper bounds on the new variables.

xctype

Type of the new variables.

cnames

Names of the new variables.

Value

Zero if successful, otherwise nonzero.

Details

Interface to the C function newCols which calls the CPLEX function CPXnewcols.
