Equation in Matrix
I have problem in center of Terwilliger Algebra. But, I will explain simple problem for simplicity my problem.
For example, I have matrix
A=Matrix([[a1,a2],[a3,a4]]);
and also I have
B1=Matrix([[1,0],[0,0]]);B2=Matrix([[0,1],[0,0]]);B3=Matrix([[0,0],[1,0]]);B1=Matrix([[0,0],[0,1]]);
These matrix have condition
AB=BA
for any B=B1,B2,B3,B4
If I solve it by hand, it is easy to get a1,a2,a3,a4
. But how to do it by sage? Can sage solve it? Thanks
