Finding centraliser algebras of a finite set of matrices

Let S be a finite set of n×n-matrices over a field K (lets say finite or the real or complex field).

Is it possible to obtain the K-algebra (or at least its vector space dimension) of n×n-matrices X in Sage with XY=YX for all YS?

(I can only think of a way for doing this for finite field with very small n by looking at all elements,but maybe there is a better technique in Sage)
