Definition of Superdiagonal. Meaning of Superdiagonal. Synonyms of Superdiagonal

- In geometry, a diagonal is a line segment joining two vertices of a polygon or polyhedron, when those vertices are not on the same edge. Informally, any...
- A diagonal matrix is one whose off-diagonal entries are all zero. A superdiagonal entry is one that is directly above and to the right of the main diagonal...
- off-diagonal entry equal to 1, immediately above the main diagonal (on the superdiagonal), and with identical diagonal entries to the left and below them. Let...
- subdiagonal, and a lower Hessenberg matrix has zero entries above the first superdiagonal. They are named after Karl Hessenberg. A Hessenberg decomposition is...
- diagonal. Hence, this matrix is not diagonalizable. Since there is one superdiagonal entry, there will be one generalized eigenvector of rank greater than...
- only if T is similar to a matrix whose only nonzero entries are on the superdiagonal(this fact is used to prove the existence of Jordan canonical form)....
- diagonal, which is filled with λ {\displaystyle \lambda } and for the superdiagonal, which is composed of ones. Any block diagonal matrix whose blocks are...
- finite-dimensional case. Because there are non-zero entries on the superdiagonal, equality may be violated. The quasinilpotent operators is one class...
- diagonal elements, and two of length n − 1 containing the subdiagonal and superdiagonal elements. The discretization in space of the one-dimensional diffusion...
- eigenvalues on the leading diagonal, and either ones or zeroes on the superdiagonal – known as Jordan normal form. Some matrices are not diagonalizable...
