Determinant value of symmetric matrix
WebThe determinant of a tridiagonal matrix A of order n can be computed from a three-term recurrence relation. Write f 1 = a 1 = a 1 (i.e., f 1 is the determinant of the 1 by 1 matrix consisting only of a 1), and let = . The sequence (f i) is called the continuant and satisfies the recurrence relation = with initial values f 0 = 1 and f −1 = 0. The cost of computing …

Web1. Yes, eigenvalues only exist for square matrices. For matrices with other dimensions you can solve similar problems, but by using methods such as singular value decomposition (SVD). 2. No, you can find eigenvalues for any square matrix. The det != 0 does only apply for the A-λI matrix, if you want to find eigenvectors != the 0-vector.
