I think you can check if two matrices are similar by checking their Jordan canonical forms. If they have the same structure, then the two matrices are similar. To find the Jordan canonical form of a matrix, you can use the MATLAB function
[V,J] = jordan(A)

you can check with a tolerance:
tol=0.0001;%tolerance
if sqrt(sum(sum((B-S*A/inv(S)).^2)))<=tol
disp('It is true')
else
disp('It is false')
end
