Graphing eigenvectors
http://cs.yale.edu/homes/spielman/561/2009/lect02-09.pdf WebJun 1, 2005 · The spectral approach for graph visualization computes the layout of a graph using certain eigenvectors of related matrices. Two important advantages of this approach are an ability to compute optimal layouts (according to specific requirements) and a very rapid computation time.

WebThis applet aims to help visualize the geometrical interpretation of the eigenvector (s) and eigenvalue (s) of a 2-by-2 matrix. In this applet, users may - define the 2-by-2 matrix by entering the values of the elements, - … 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.
