class BlockMatrix[RowT, GroupT, ColT, ValT] extends AnyRef

BlockMatrix is 3 dimensional matrix where the rows are grouped It is useful for when we want to multiply groups of vectors only between themselves. For example, grouping users by countries and calculating products only between users from the same country
