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

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

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.

Details

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

Value

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