NAG_OPT_QP

 
Solves general quadratic programming problems. It is not intended for large
sparse problems.
 
Classes  :  G2a1 . Linear programming with a dense matrix of constraints
            G2e1 . Quadratic programming for positive definite Hessians
                 (i.e., convex problems)
            G2e2 . Quadratic programming for indefinite Hessians
            G4d .  Find feasible point for optimization
 
Type     : C subroutine in NAGC library (E04 sublibrary).
Access   : Proprietary. Many implementations available.
Precision: Double.
Note     : This procedure may also be invoked using the name e04nfc.
 
Usage    : void nag_opt_qp(Integer n, Integer nclin, double a[], Integer tda,
           double bl[], double bu[], double cvec[], double h[], Integer tdh,
           void (*qphess)(Integer n, Integer jthcol, double h[], Integer tdh,
           double x[], double hx[], Nag_Comm *comm), double x[], double *objf,
