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

[dave fournier]

Thinking about this a bit more you should look at the shell script for
compiling for your platform. It will tell you what macros to define and what
libraries to link with for the safe and optimized versions.

Then the boiler plate you need in your C++ code is something like what I have below.



     main()
     {

          // whatever

         gradient_structure gs(100000000);  // makes the data strctures for AD
         int nvar=1000;   // 1000 independent variablesu
         
         dvector g(1,n);  // this will hold the gradient vector
          independent_variables x(1,n);

           dvar_vector vx=dvar_vector(x);

             // the code for evaluating the function

           gradcalc(nvar,g); // calculates the gradient
          
            cout << g << endl;  // take a look at the gradient
           
       }
