}Expand description
A confidence ellipse from an arbitrary 2x2 covariance block.
Domain-neutral companion to HorizontalErrorEllipse: the axes carry
whatever unit the covariance is in (square that unit), and orientation_rad
is the semi-major-axis direction measured from the first axis toward the
second.
Fields§
§confidence: f64Requested confidence probability in (0, 1).
chi_square_scale: f64Two-degree-of-freedom chi-square scale -2 ln(1 - confidence) applied to
the covariance eigenvalues.
semi_major: f64Semi-major axis length (same unit as the square root of the covariance).
semi_minor: f64Semi-minor axis length.
orientation_rad: f64Semi-major-axis orientation in radians, from the first (row/col 0) axis toward the second (row/col 1) axis.
