public int CPXgetnumqpnz(CPXCENVptr env, CPXCLPptr lp)

Definition file: cplex.h

The routine CPXgetnumqpnz returns the number of nonzeros in the Q matrix of a problem object.

Example

 numqpnz = CPXgetnumqpnz (env, lp);

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
lp	A pointer to a CPLEX problem object as returned by `CPXcreateprob`.

If successful, the routine returns the number of nonzeros in the Q matrix. If an error occurs, zero is returned.
