    For help on the process, see Wikipedia:How to draw a diagram with Inkscape. This tutorial aims to instruct a beginner on the basic principles of vector graphics using Microsoft Word (Office 97 or later). The basic principles are the same in other drawing programs such as CorelDraw or the free and open source OpenOffice.org.

    en.wikipedia.org/wiki/Eigendecomposition_of_a_matrix

    Let A be a square n × n matrix with n linearly independent eigenvectors q i (where i = 1, ..., n).Then A can be factored as = where Q is the square n × n matrix whose i th column is the eigenvector q i of A, and Λ is the diagonal matrix whose diagonal elements are the corresponding eigenvalues, Λ ii = λ i.

  4. Eigenvalues and eigenvectors - Wikipedia

    en.wikipedia.org/wiki/Eigenvalues_and_eigenvectors

    The eigenspaces of T always form a direct sum. As a consequence, eigenvectors of different eigenvalues are always linearly independent. Therefore, the sum of the dimensions of the eigenspaces cannot exceed the dimension n of the vector space on which T operates, and there cannot be more than n distinct eigenvalues. [d]

    This method works only if your molecule editor is able to export files in Windows Metafile format. For example, ChemDraw supports this, as does ChemSketch and BIOVIA Draw (.emf is preferable for the latter). Draw the structure in your molecule editor, and save it as a Windows Metafile (.wmf), Enhanced Metafile (.emf), or Encapsulated Postscript ...

  7. Arnold's cat map - Wikipedia

    en.wikipedia.org/wiki/Arnold's_cat_map

    The eigenspaces are orthogonal because the matrix is symmetric. Since the eigenvectors have rationally independent components both the eigenspaces densely cover the torus. Arnold's cat map is a particularly well-known example of a hyperbolic toral automorphism , which is an automorphism of a torus given by a square unimodular matrix having no ...
