gamma2z with Zref complex

Hi, gamma2z works well with Zref real but not when using a complex number. I can not find the proper eqn ..anyone knows where to find it ?

What happens when you use a complex zref ?

The algorithm documented appear to agree with literature I find

[michael]

you get a wrong answer ...most of the so call "literature" available on the web use a simplified eqn for Zref = real #, with Zref = complex the eqn is a bit more complex. l checked with ADS and their "stoz" function, they are using the correct one.
