The problem is coming from this line:

auxd = (rho^(j-1))*shiftr(lhs[.,2]',-j,0)';

In your code, lhs does not exist. You will get the error: G0064 : Operand missing if you try to index into a variable that does not yet exist. For example:

print non_existant_var[.,1];

will give the error G0064 : Operand missing.
