Since I need a spline interpolation I used your library do calculate it but it seems it is not working good.
If I understood javadoc i need two double[] arrays: - double[] x: the absissa of every point - double[] y: the ordinate/value of points in the same order of x Now after interpolation I try to print it through: System.out.println(Arrays.toString(interpolation.getPolynomials())); where interpolation is the PolynomialSplineFunction generated. It outputs some functions but only the first is correct, why? Thank you!
