Thanks David for your response, some interesting reads there, especially as I may have to look into errors and noise variation in my data at a later stage.

I dont wish to find a new method (though the Newton-Rapshon one seems interesting) for now Im just trying to work out how to 

a) use plot3 to plot many circles together in 3d space, which are of the form:-

 Q = P + R*u*cos(s) + R*v*sin(s)
where s is an (angular) parameter and Q an arbitrary point on the circle. u,v are necessary orthogonal vectors, 

as that is the way I have already coded and successfully calculated the necessary parts, from my data

and b) attempting to find potential intersections betweens these circles 

Thanks again
