  copyStartCPLEX(env, lp,
                 cstat = NULL, rstat = NULL,
                 cprim = NULL, rprim = NULL,
                 cdual = NULL, rdual = 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.

cstat

A vector containing the basis status of the columns in the constraint matrix.

rstat

A vector containing the basis status of the slack, surplus, or artificial variable associated with each row in the constraint matrix.

cprim

A vector containing the initial primal values of the column variables.

rprim

A vector containing the initial primal values of the slack (row) variables.

cdual

A vector containing the initial values of the reduced costs for the column variables.

rdual

A vector containing the initial values of the dual variables for the rows.

Details

Interface to the C function copyStart which calls the CPLEX function CPXcopyStart.

Value

Zero if successful, otherwise nonzero.
