This is an example of using NOX with the NOX::LAPACK::Group and NOX::LAPACK::Vector classes. These are very basic classes intended only to illustrate and test NOX. They are based on a combination of C++ STL and LAPACK.

This example is the "%Rosenbrock function" from Jorge J. More', Burton S. Garbow, and Kenneth E. Hillstrom, Testing Unconstrained Optimization Software, ACM TOMS, Vol. 7, No. 1, March 1981, pp. 14-41.

It comes originally from H. H. Rosenbrock, An Automatic Method for Finding the Greatest or Least Value of a Function, J. Comput. 3(1960):175-184.

The function is defined as

The initial guess is given by

The solution is
