[GiNaC-list] Clifford Metric Array

[Alan Bromborsky]

You probably handle this correctly internally, but the documentation 
example is not consistent.  In section 4.15.1.2, "A Generic Clifford 
Algebra", you state that e[i]*e[j]+e[j]*e[i] = M(i,j) and then give an 
example where
     ex M = diag_matrix(lst(1,-1,0,s));
     ex e = clifford_unit(nu,M);

and say M(0,0) = 1 -> e[0]^2 = 1.  I get 2*e[0]^2 = 1 so that e[0]^2 = 
1/2.  Is M internally multiplied by 2?
