checkAddColsCPLEX: Validate Arguments of the Corresponding addColsCPLEX Routine

Description

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

Usage

checkAddColsCPLEX(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.

Value

Nonzero if it detects an error in the data; it returns zero if it does not detect any data errors.

Details

Interface to the C function checkAddCols which calls the CPLEX function CPXcheckaddcols.
