Oliver Kent of Muirhead Aerospace Ltd recently commented on my formula for twisted-pair line impedance (Figure 1). “I am using coated wire with 1.3-mm outer diameter and 0.95-mm inner diameter,” Kent ...

The FD= and FDHESSIAN= options specify the use of finite difference approximations of the derivatives. The FD= option specifies that all derivatives are approximated using function evaluations, and ...
