addQConstrCPLEX: Add Quadratic Constraint 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 CPXaddqconstr. Consult the IBM ILOG CPLEX documentation for more detailed information.

Usage

  addQConstrCPLEX(env, lp, lzn, qzn, rhs, sense,
                  lind = NULL, lval = NULL,
                  qrow, qcol, qval, qname = 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.
lzn	Number of nonzero constraint coefficients in the linear part of the constraint.
qzn	Number of nonzero constraint coefficients in the quadratic part of the constraint.
rhs	Righthand side term.
sense	The sense of the constraint to be added. Consult the IBM ILOG CPLEX documentation for more detailed information.
lind	Linear part of the quadratic constraint to be added. Consult the IBM ILOG CPLEX documentation for more detailed information.
lval	Linear part of the constraint to be added. Consult the IBM ILOG CPLEX documentation for more detailed information.
qrow	Quadratic part of the quadratic constraint to be added. Consult the IBM ILOG CPLEX documentation for more detailed information.
qcol	Quadratic part of the quadratic constraint to be added. Consult the IBM ILOG CPLEX documentation for more detailed information.
qval	Quadratic part of the quadratic constraint to be added. Consult the IBM ILOG CPLEX documentation for more detailed information.
qname	Name of the constraint to be added.

Details

Interface to the C function addQConstr which calls the CPLEX function CPXaddqconstr.

Value

Zero if successful, otherwise nonzero.
