Conclusions

The basic IGF90 building blocks work fine: constructors, member functions, linear operators, chained operators, block operators, and linear solvers. We have shown working examples of the IGF90 class and its interface to the HCL library of optimization algorithms. We have developed an interface to encapsulate Fortran90 data structures and operators within C++. We have discussed here the design of the C++/Fortran90 interface, as well as showed examples of the C++ interface to SEPlib90 data structure and the interface to a Fortran90 linear interpolation operator.
