[ADMB Users] How to use Autodif as a regular external C++ library?

[dave fournier]

I was curious to see if you needed to change struct to class.
It appears not. But you do need to use new and delete
as this simple example shows.


#include <fvar.hpp>

struct mys
{
   dvariable x;
};

main()
{
   gradient_structure gs(1000000);

   // this will work
   mys u;
   u.x=5;
   cout << u.x << endl;

   // this will work
   mys * pu2 = new mys;
   pu2->x=7;
   cout << pu2->x << endl;
   delete pu2;
   pu2=0;

   // this will crash
   mys * pu=(mys*) malloc(sizeof(mys));
   pu->x=6;
   cout << pu->x << endl;
}
