Hi Everyone,

This is a question regarding the C++ interface, specifically how to use the
class IpoptCalculatedQuantities.  I am trying to get the Ipopt calculated
Hessian at the optimal point so that I can use it downstream for some
further analysis.

I got as far as

where ip_cq is a pointer to

but how do I get the values out of the matrix?

Thank you.
