Commuting matrices

In linear algebra, two matrices $A$ and $B$ are said to commute if $AB=BA$ and equivalently, their commutator $[A,B]= AB-BA$ is zero. A set of matrices $A_1,\ldots,A_k$ is said to commute if they commute pairwise, meaning that every pair of matrices in the set commute with each other.
