The notation Matn⁡(𝕂) is often used to signify the set of square matrices which are of order n (size n×n) with elements drawn from a field 𝕂. Thus, one would use a∈Mat3⁡(ℂ) to declare that a is a three-by-three matrix with elements that are complex numbers.

Property: Suppose A and B are matrices such that A⁢B is a square matrix. Then the product B⁢A is defined and also a square matrix.
