Eigenvectors of a diagonal matrix
WebD = pageeig (X) returns the eigenvalues of each page of a multidimensional array. Each page of the output D (:,:,i) is a column vector containing the eigenvalues of X (:,:,i). Each page of X must be a square matrix. example. [V,D] = pageeig (X) computes the eigenvalue decomposition of each page of a multidimensional array. WebIf the covariance matrix of our data is a diagonal matrix, such that the covariances are zero, then this means that the variances must be equal to the eigenvalues . This is illustrated by figure 4, where the eigenvectors are shown in green and magenta, and where the eigenvalues clearly equal the variance components of the covariance matrix.

WebSep 17, 2024 · In this module we exploit the fact that the matrix exponential of a diagonal matrix is the diagonal matrix of element exponentials. In order to exploit it we need to recall that all matrices are almost diagonalizable. Let us begin with the clean case: if A is n-by-n and has n distinct eigenvalues, λj, and therefore n linear eigenvectors, sj ... WebRecall (Theorem 5.5.3) that an n×n matrix A is diagonalizable if and only if it has n linearly independent eigenvectors. Moreover, the matrix P with these eigenvectors as columns is a diagonalizing matrix for A, that is P−1AP is diagonal. As we have seen, the really nice bases of Rn are the orthogonal ones, so a natural questionis: which n×n
