Controls

A matrix warps the unit circle into an ellipse. Eigenvectors are the special directions that only stretch — never rotate — by their eigenvalue.

Governing equation

A = [2.0 1.0 1.0 2.0], A v = λ v, det (A - λ I) = 0, λ = 3.00, 1.00

Reading this result: Symmetric matrix (b = c): its eigenvectors meet at right angles, so the ellipse axes line up exactly with the green and pink lines.
