grss.prop.prop_utils.data_to_ellipse(x_data, y_data, n_std, bplane_type, print_ellipse_params, units, sigma_points)#

Convert two sets of points to an ellipse.

Parameters:
  • x_data (np.ndarray) – x-coordinates of the points

  • y_data (np.ndarray) – y-coordinates of the points

  • n_std (float, optional) – Number of standard deviations to plot

  • bplane_type (str) – type of B-plane

  • print_ellipse_params (bool, optional) – True to print the ellipse parameters, False to not print

  • units (str) – units of the plot

  • sigma_points (prop.SigmaPoints, optional) – SigmaPoints object for reconstructing mean and cov, by default None.

Returns:

  • mean (np.ndarray) – mean of the data

  • ellipse (np.ndarray) – ellipse points
