%description
Several tools for handling block-matrix diagonals and similar constructs
are implemented. Block-diagonal matrices can be extracted or removed using
two small functions implemented here. In addition, non-square matrices are
supported. Block diagonal matrices occur when two dimensions of a data set
are combined along one edge of a matrix. For example, trade-flow data in
the 'decompr' and 'gvc' packages have each country-industry combination
occur along both edges of the matrix.
