addDatasetToGaussianFitter

protected static void addDatasetToGaussianFitter(double[][] points,
                                                 GaussianFitter fitter)

Adds the specified points to specified GaussianFitter instance.

Parameters:

points - data points where first dimension is a point index and second dimension is an array of length two representing the point with the first value corresponding to X and the second value corresponding to Y

fitter - fitter to which the points in points should be added as observed points
