addColsCPLEX: Adds Columns to a Specified CPLEX Problem Object

In cplexAPI: R Interface to C API of IBM ILOG CPLEX

Description

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

Usage

  addColsCPLEX(env, lp, ncols, nnz, objf, matbeg, matind, matval,
               lb = NULL, ub = 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 columns.
nnz	Number of nonzero constraint coefficients.
objf	Objective function coefficients.
matbeg	Array that specifies the nonzero elements of the columns being added. Consult the IBM ILOG CPLEX documentation for more detailed information.
matind	Array that specifies the nonzero elements of the columns being added. Consult the IBM ILOG CPLEX documentation for more detailed information.
matval	Array that specifies the nonzero elements of the columns being added. Consult the IBM ILOG CPLEX documentation for more detailed information.
lb	Lower bounds of the new variables.
ub	Upper bounds of the new variables.
cnames	Names of the new variables.

Details

Interface to the C function addCols which calls the CPLEX function CPXaddcols.

Value

Zero if successful, otherwise nonzero.
