Triangulation using sphere intersects

Im trying to triangulate locations in xyz space.

I have locations for the centre of spheres and what can be thought of as radii, so what is the best way with Matlab to compute intersects to
1) get and plot the circle where 2 spheres intersect or
2) get and plot the 2 points where 3 spheres may intersect.

Many Thanks
Greg
