A colleague is developing an instrument to measure CO2 and oxygen concentration in the International Space Station.

In order to do that, he needs to invert a nonlinear function.

The usual way to do that is a Newton-Levenberg-Marquardt iteration.

Many numerical libraries have software for it in Fortran or C.

Does anybody have a highly-reliable Newton-Levenberg-Marquardt method in Ada?
