matrix algebra

The associative algebra of matrices over some ring under matrix multiplication is the coresponding *matrix algebra*.

The algebra of $n \times n$-matrices is equivalently the groupoid convolution algebra of the pair groupoid on the set with $n$-elements.

The matrix algebra over a normed ring is naturally itself a normed ring. See at *normed ring – Examples – matrix ring*.
