A block matrix is a matrix whose elements are matrices of a smaller size.
Partitioning a matrix into blocks is often helpful in applying matrix operations because it reduces the operations into those of smaller matrices, which is often easier to do.
A handy class of block matrices is matrices consisting of column vectors.
