Block Matrix/Examples/Arbitrary 1

Example of Block Matrix
Let $\mathbf A = \sqbrk a_{m n}, \mathbf B = \sqbrk b_{m p}, \mathbf C = \sqbrk c_{r n}, \mathbf D = \sqbrk d_{r p}$.

The $\paren {m + r} \times \paren {n + p}$ block matrix $\mathbf M$: can then be created as:


 * $\mathbf M = \begin{bmatrix}

\mathbf A & \mathbf B \\ \mathbf C & \mathbf D \end{bmatrix}$
