WebApr 12, 2024 · To parameterize the 2 × 2 variance matrix Σ, we employ its principal values, σ 1 2 and σ 2 2, and the angle θ between the principal direction for σ 1 2 and the axis of coordinate x +. For θ = 0, the x + and x − coordinates are independently distributed and also dynamically uncoupled since according Eq. , the diffusion matrix is diagonal.
