Commutator.jl

This package provides the function commutator! that calculates the commutator [A, B] of two ring elements A, B. That is,

commutator!(alpha, A, B, beta, C)

evaluates in-place to

C = beta * C + alpha * (A * B - B * A)

Typically, A, B, C are subclasses of AbstractMatrix, and beta and alpha are a Number.
