There is a small bug in the lambda:

You want the vector to be passed by reference not
Hi, thanks! that worked by using polar.objective_fun(a,b), instead of
Callback.
Now, it seems that SolverBFGS is not starting, and terminates in the first
function call!
However, the optimization should not be done since |grad x| is not small.
This is what I do:
Vector X (N), Dx (N);
Here is a simple example:
https://wandbox.org/permlink/fbcldo9PIiHl6tfI In your case, try
something like
auto my_lambda = [&polar](Vector a, Vectorb) {return
polar.Callback(a,b);};
opt.solve ( my_lambda, X );

Thanks Bruno for your prompt reply,
I got the important part of the code compiling, however since I am new to
this lambda (functional) functions, I do not know how to pass the new
definitions to SolverBFGS.
Looking at your suggestion I do the following:
class Shape_compute {

Juan,
Take a look at

I advise using a lambda like the second reply suggests
Best,
