WebSuppose vectors v and cv have eigenvalues p and q. So Av=pv, A (cv)=q (cv) A (cv)=c (Av). Substitute from the first equation to get A (cv)=c (pv) So from the second equation, q (cv)=c (pv) (qc)v= (cp)v Since v is an eigenvector, it cannot be the 0 vector, so qc=cp, or q=p.

WebMar 26, 2024 · The Eigenvector is the direction of that line, while the eigenvalue is a number that tells us how the data set is spread out on the line which is an Eigenvector. WebYou could extract the eigenvectors and -values via eigen (A). However, it's simpler to use the Cholesky decomposition. Note that when plotting confidence ellipses for data, the ellipse-axes are usually scaled to have length = square-root of the corresponding eigenvalues, and this is what the Cholesky decomposition gives.
