Indeed it may be worth to see a difference in the output for Clifford units with different representation labels. I include a patch which give this in the way which is shown by such an example: #include <ginac/ginac.h> using namespace std; using namespace GiNaC; int main() { try { varidx mu(symbol("nu", "\\nu"), 3); ex basis1 = clifford_unit(mu, diag_matrix(lst(1, 1, 1)),0), basis2 = clifford_unit(mu, diag_matrix(lst(1, 1, 1)),1); ex e00 = basis1.subs(mu == 0), e10 = basis2.subs(mu == 0); cout << e00 << endl; // <-- e~0 cout << e10 << endl; // <-- e[1]~0 } catch (exception &p) { cerr << "Got problem: " << p.what() << endl; } } Best wishes, Vladimir -- Vladimir V.
