checkChgCoefListCPLEX: Validate Arguments of the Corresponding chgCoefListCPLEX Routine

Description

Low level interface function to the IBM ILOG CPLEX function CPXcheckchgcoeflist. Consult the IBM ILOG CPLEX documentation for more detailed information.

Usage

checkChgCoefListCPLEX(env, lp, nnz, ia, ja, ra)

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.

nnz

Number of nonzero constraint coefficients.

ia

Row indices of the nonzero elements.

ja

Column indices of the nonzero elements.

ra

Nonzero elements.

Value

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

Details

Interface to the C function checkChgCoefList which calls the CPLEX function CPXcheckchgcoeflist.
