Yes I only want to find center and radius. And these equations do look like they will work. But I have a few, last possibly elementary questions abt this circle module.

Since the inputs I have are complex numbers z0,z1,z2 and these equations need me to add the squares of the coordinates. For instance eqn 32 for d has x1^2 + y1^2 as one of the matrix elements.
So in my case should I put Re[zo]^2 + Im[z0]^2 etc and will that work?

And arent these variables a,d,e,f equal to determinants? So that calls for first defining the matrices then using Det command?
Your help is much appreciated :)
