Usage

1
  getQPcoefCPLEX(env, lp, i, j)

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.

i

The row number in Q.

j

The row column in Q.

Details

Interface to the C function getQPcoef which calls the CPLEX function CPXgetqpcoef.

Value

Specified quadratic coefficient in the matrix Q if successful, otherwise an instance of class "cplexError".
