chgColsBndsCPLEX: Change Lower and Upper Bounds on a Set of Variables of a...

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

Description

Set lower and upper bounds on a set of variables in one step. If lb[i] == ub[i] the type of the bound is set to "B", otherwise lb[i] is set to "L" and ub[i] is set to "U".

Usage

  chgColsBndsCPLEX(env, lp, j, lb, ub)

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.
j	An integer that specifies the numeric index of the column in which the coefficient is located.
lb	A vector containing the lower bounds.
ub	A vector containing the upper bounds.

Details

Interface to the C function chgColsBnds which calls the CPLEX function CPXchgbds.

Value

Zero if successful, otherwise nonzero.
