CPXcopyqpsep

Description

The routine CPXcopyqpsep() is used to copy a Q matrix for separable QP problems. A separable QP problem is one where the coefficients of Q have no nonzero off-diagonal elements.

CPLEX evaluates the corresponding objective with a factor of 0.5 in front of the quadratic objective term.

The routine returns a zero on success, and a nonzero if an error occurs.

int CPXcopyqpsep (CPXCENVptr env, CPXLPptr lp, const double *qsepvec);

Arguments

The pointer to the CPLEX environment as returned by CPXopenCPLEX().

A pointer to a CPLEX problem object as returned by CPXcreateprob().

An array of length CPXgetnumcols(env,lp).qsepvec[0], qsepvec[1],..., qsepvec[numcols-1] should contain the quadratic coefficients of the separable quadratic objective.

status = CPXcopyqpsep (env, lp, qsepvec);
