The normal \(\Delta\) H-matrices with connection to some Jacobi-like methods
The paper gives conditions for normal \(\Delta\) H matrices of order n (general or attractive) to be diagonal. A complete description of the normal \(\Delta\) H matrices for \(n=3\), and some results for \(n=4\), are also given.
