Eigenvectors: the axis a matrix does not rotate
Most vectors change both direction and length after multiplying by a matrix — they get rotated and stretched. But every matrix has special vectors — eigenvectors — that are only scaled, not rotated. They are the matrix's “axes of symmetry.” The factor by which the vector is stretched is the eigenvalue λ.
