In the (point-wise) H-matrix case, it was proven that the diagonal entries solely reveal this information. This paper generalises these results to the block H-matrix cases for 1, 2, and ∞ matrix norms. The usefulness of the block approach is illustrated on 3 relevant numerical examples, arising in engineering.
