getColInfeasCPLEX: Compute Infeasibility of a Given Solution for a Range of Variables

Description

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

Usage

getColInfeasCPLEX(env, lp, begin, end, sol = 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.

begin

An integer specifying the beginning of the range of variables whose infeasibility is to be returned.

end

An integer specifying the end of the range of variables whose infeasibility is to be returned.

sol

The solution whose infeasibility is to be computed.

Value

infeasibility values if successful, otherwise an instance of class "'>cplexError".

Details

Interface to the C function getColInfeas which calls the CPLEX function CPXgetcolinfeas.
