Modifier and Type	Method	Description
static void	Approximator.approximateFX(double[][] data, int[] indices, FX[] f, double[] c)	Solves a linear equation system with each term having the form c * f(x).
static double	Approximator.computeY(FX[] f, double[] c, double x)	Computes y(x) = sum(c[i] * f[i](x), i = 0, n - 1).
static double	Approximator.getRMSE(double[][] data, int[] indices, FX[] f, double[] c)	Returns the root mean square error (RMSE) for the approximation of the given data with a function given by y'(x) = c[0]*f[0](x) + c[1]*f[1](x) + c[2]*f[2](x) + ...
