The core idea of eigenvectors and eigenvalues emerges early on [] as special vectors that, when subjected to a linear transformation (represented by a matrix), only get stretched or squished, remaining on their original span. This means the transformation's effect on these vectors is purely scalar multiplication. For instance, a specific example demonstrates vectors on the x-axis being scaled by 3, and others on a diagonal line being scaled by 2, with these scaling factors being the eigenvalues [-]. This property is fundamental because it simplifies understanding a transformation's essence, independent of the coordinate system used, unlike reading matrix columns alone [].
