Komplex is a package for solving complex-valued linear systems of equations using equivalent real formulations. Komplex converts the original complex-valued problem into a rel-valued problem of twice the dimension and then solves the problem using one o many real-valued solvers. Although most applicatons primarily generate real-valued linear systems of equations, numerous applications have the need to solve complex valued problems, at least occasionally. Komplex provides a low-cost approach to solving complex systems by converting the complex problem to an equivalent real system and then using the real-valued solvers already installed in the application to solve the equivalent real system. By writing the complex-valued problem in its real and imaginay parts, we can form a variety of equivalent real-valued systems of twice the dimension. Komplex performs this conversion in an intelligent way and then solves the real-valued system using some other real-valued solver, such as AztecOO.
