I have these 3D data (attached) which represents the points of an ellipse or a circle (it is not exactly a circle).
How can I find the centre and the radius of this ellipse ?

You can download this,
and use ellipticalFit().
load('ellipse_circle_3Ddata.mat')
pFit=planarFit(data);
eFit=ellipticalFit(pFit.project2D(data))
Center3D=pFit.unproject3D(eFit.center(:))'
efit =
ellipticalFit with properties:
center: [1.9450e+05 7.1093e+04]
a: 2.6560e+07
b: 2.6559e+07
angle: 15.8694
Center3D =
1.0e+05 *
-1.2707 1.6117 -0.2764
