A matrix with too few eigenvectors is not a diagonalizable matrix. One example of when that happens is point 3. above. But there's more! As opposed to eigenvalues, a matrix's eigenvectors don't have multiplicities. It may, however, happen that, say, an eigenvalue of multiplicity 22 has...
Diagonalizing a Matrix: Diagonalizing a matrix involves finding an invertible matrix that diagonalizes the matrix. The invertible matrix is determined by finding the eigenvectors of the matrix. The resulting diagonal matrix contains diagonal elements which are the eigenvalues of th...
Summary: We consider a Vandermonde factorization of a Hankel matrix, and propose a new approach to compute the full decomposition in $O(n^2)$ operations. The method is based on the use of a variant of the Lanczos method to compute a tridiagonal matrix whose eigenvalues are the modes ...
In particular, if P is orthogonal, that is, P⊤P=I, then we say that A is orthogonally diagonalizable. The diagonalization of a matrix has many applications in solving systems of equations.Answer and Explanation: Compute the ...
Given an upper triangular matrix A∈ Rn×n and a tolerance τ, we show that the problem of finding a similarity transformation G such that G−1AG is block diagonal with the condition number of G being at most τ is NP-hard. Let ƒ(n) be a polynomial in n. We also show that ...
Eigenvalues are the scalar value associated with an eigenvector, represented by the symbol lambda (λ). To find eigenvalues, use the following equation:[1] In other words, the determinant of lambda times the identity matrix minus the given transformation matrix. 2 Set up the determinant equatio...
