Detailed Description

Struct for zero and explicit first order quantities that subclass must fill in.

When computing Gc and/or Gh, the subclass can be instructed to set the row and columns index arrays by setting Gc_ivect!=NULL and/or Gh_ivect!=NULL respecitively.

Objects of this type are passed on to subclasses and contain pointers to quantities to be updated. Note that NLP subclasses are not to resize the DVector or std::valarray objects Gc_val, Gc_ivect, Gc_jvect, Gh_val, Gh_ivect, Gh_jvect, *Gf, *c or h since the these will already be resized.

The storage format for the gradient matrices Gc and Gh use the coordinate data structure. For Gc, for instance, the elements are stored as:

   for k = 0 ... Gc_nz
       Gc(Gc_ivect[k],Gc_jvect[k]) == Gc_val[k]
   

and all of the other matrix entries in Gc are implicitly zero.

In general, it is allowed for duplicate entries (Gc_ivect[k],Gc_jvect[k]) to exist with the convention that the corresponding Gc_val[k] are to be added in matrix operations. This is a relaxed requirement that can make things much more complicated for the code that accesses these matrix entries.
