Curve Fitting toolbox: is it possible to get back circle from scattered 3d points?

I'm wonder if MatLab has ability to restore circle from 3D scattered points:

    center point
    radius
    normal vector.

Screen shot can be seen from here (it should be 3d!): https://en.wikipedia.org/wiki/File:Least_square_conic.png

Second question: some points might be too far from scattered points. Is it possible to filter those out using MatLab?
