Eigenvectors of acyclic matrices
Web[2] computes the Fourier basis as the matrix of eigenvectors of the adjacency matrix, with a frequency ordering determined by a total variation measure based on the adjacency matrix. Alternatively, the Jordan canonical form is used if the adjacency matrix cannot be di-agonalized, which is often the case with directed graphs that have WebAn matrix with linearly independent eigenvectors can be expressed as its eigenvalues and eigenvectors as: The eigenvector matrix can be inverted to obtain the following similarity transformation of : Multiplying the matrix by on the left and on the right transforms it into a diagonal matrix; it has been ‘‘diagonalized’’.
