  checkAddRowsCPLEX(env, lp, ncols, nrows, nnz, matbeg, matind, matval,
                    rhs = NULL, sense = NULL,
                    cnames = NULL, rnames = 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.

ncols

Number of new columns in the constraints being added to the constraint matrix.

nrows

Number of rows.

nnz

Number of nonzero constraint coefficients.

matbeg

An array used with rmatind and rmatval to define the rows to be added. Consult the IBM ILOG CPLEX documentation for more detailed information.

matind

An array used with rmatind and rmatval to define the rows to be added. Consult the IBM ILOG CPLEX documentation for more detailed information.

matval

An array used with rmatind and rmatval to define the rows to be added. Consult the IBM ILOG CPLEX documentation for more detailed information.

rhs

Righthand side term for each constraint to be added.

sense

Sense of each constraint to be added.

cnames

Names of the new columns.

rnames

Names of the new rows.

Details

Interface to the C function checkAddRows which calls the CPLEX function CPXcheckaddrows.

Value

Nonzero if it detects an error in the data; it returns zero if it does not detect any data errors.
