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

1	getQPcoefCPLEX(env, lp, i, j)

`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.

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

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