[GiNaC-list] symbolic matrix

[Luis Rivera]

Hello Vladimir,

Thanks for your answer. Yes, if I use the code below it works.
Could you explain me in few words why it should be so?

Thanks,

Luis

New version:

###########
	ex A; 
	A = symbolic_matrix(n,n, "A");
	cout << "A(0,0) = " << ex_to<matrix>(A)(0,0) << endl;
	cout << "A(0,1) = " << ex_to<matrix>(A)(0,1) << endl;
	cout << "A(1,0) = " << ex_to<matrix>(A)(1,0) << endl;
	cout << "A(1,1) = " << ex_to<matrix>(A)(1,1) << endl;
###########
