Abstract

Bases for matrix algebras Calculation of matrix algebras from generators Dimension of matrix algebras
We give an efficient solution to the following problem: Given X1,…Xd and Y some n by n matrices can we determine if Y is in the unital algebra generated by X1,…,Xd as a subalgebra of all n by n matrices? The solution also gives an easy method for computing the dimension of this algebra.
