For this case, I would suggest to solve independently two 2D curves corresponding to x(z) and y(z). This can be done using org.apache.commons.math3.fitting.PolynomialCurveFitter if you consider your curves will be polynomials, or you can use your own extension of AbstractCurveFitter if you prefer your own non-polynomial model for curves. See <http://commons.apache.org/proper/commons-math/userguide/fitting.html#a17.2_Implemented_Functions> for an example of how to fit a polynomial to observed data. > > Any advice if very appreciated.
